Class Enemy is a 1978 play by the British playwright Nigel Williams which premiered at the Royal Court Theatre. Class Enemy was written in 1978 as a social commentary on the apathy and anarchy in inner city British schools, is adapted to the new European reality at the beginning of the 21st century. The set is a bleak classroom with broken tables and chairs, dirty blackboard and lit with sterile fluorescent lamps. The play starts with six students waiting for a teacher and, like Samuel Beckett’s Vladimir and Estragon, they seem to wait in vain.

Class II PI 3-kinases are a subgroup of the enzyme family, phosphoinositide 3-kinase that share a common protein domain structure, substrate specificity and method of activation. Class II PI 3-kinases were the most recently identified class of PI 3-kinases and little is currently known about these enzymes. There are three class II PI 3-kinase isoforms expressed in mammalian cells;
* PI3K-C2α encoded by the PIK3C2A gene
* PI3K-C2β encoded by the PIK3C2B gene
* PI3K-C2γ encoded by the PIK3C2G gene

CLN is a free library for arbitrary precision arithmetic. It operates on signed integers, rational numbers, floating point numbers, complex numbers, modular numbers, and univariate polynomials. Its implementation programming language is C++. CLN uses object oriented techniques and operator overloading to achieve a natural algebraic syntax: The sum x of two variables a and b is written as x = a + b, as opposed to the function sum(&x, a, b).

Class analysis is research in sociology, politics and economics from the point of view of the stratification of the society into dynamic classes. It implies that there is no universal or uniform social outlook, rather that there are fundamental conflicts that exist inherent to how society is currently organized. Most known examples are the theory of Karl Marx and Max Weber's three-component theory of stratification.

An alternative model of the class council is based on work of Rudolf Dreikurs, a pupil of Alfred Adler.Dreikurs developed the class council based on individual psychology and without reference to Freinet pedagogy as an instrument of problem solving and mediation but not as an agency of self-determination.

In computing, a class driver is a type of hardware device driver that can operate a large number of different devices of a broadly similar type. Class drivers are very often used with USB based devices, which share the essential USB protocol in common, and devices with similar functionality can easily adopt common protocols. As another example, instead of having a separate driver for every kind of CD-ROM device, a class driver can operate a wide variety of CD-ROMs from different manufacturers. To accomplish this the manufacturers make their products compatible with a standardized protocol. In technical terms, a class driver is used as a base or ancestor class for specific drivers which need to have slightly different or extended functionality, but which can take advantage of the majority of the functionality provided by the class driver. This concept is a key aspect of object oriented programming, which when extended to drivers makes it much easier for hardware vendors to provide driver support for their products.

Class Reunion (original title: Der Abituriententag) is a novel by Franz Werfel first published in German in 1928.

Class collaboration is a principle of social organization based upon the belief that the division of society into a hierarchy of social classes is a positive and essential aspect of civilization.

In political theory and particularly Marxism, class consciousness is the set of beliefs that a person holds regarding their social class or economic rank in society, the structure of their class, and their class interests. According to Karl Marx, it is an awareness that is key to sparking a revolution that would "create a dictatorship of the proletariat, transforming it from a wage-earning, property-less mass into the ruling class".

In mathematics, class field theory is the branch of algebraic number theory concerned with the abelian extensions of number fields, global fields of positive characteristic, and local fields. The theory had its origins in the proof of quadratic reciprocity by Gauss at the end of 18th century. These ideas were developed over the next century, giving rise to a set of conjectures by Hilbert that were subsequently proved by Takagi and Artin. These conjectures and their proofs constitute the main body of class field theory.

Class Reunion is a popular television show broadcast in Ireland on RTÉ One. Roughly based on the British programme, This Is Your Life, the show is hosted by Gay Byrne and was broadcast on Sunday nights in early 2005. Ten shows were broadcast in the series which features a special guest who has achieved outstanding success in areas such as art, film, business or sport. The special guest is then reunited with their old classmates, and they relive old memories and stories. Guests have included Adi Roche, Mary O'Rourke, Pat Spillane and Dana. It is expected that the show may return for a second series.

In object-oriented programming, a class implementation file is often used to contain the implementation code for the method(s) of a class. This file is also referred to as a source file. Programming languages like C and C++ make use of these implementation files so as to separate the interface and implementation of these methods.

In object-oriented programming, a class is a template that defines the state and behavior common to objects of a certain kind. A class can be defined in terms of other classes.

The game was intended to teach players about the politics of Marxism, and was loosely compared the board game, Monopoly. The game pits Workers against Capitalists, represented by hammers and top hats respectively. Players receive their class by a roll of the "genetic" dice. Players move around a board following dice rolls and draw "Chance" cards which either advantage or disadvantage them.

In mathematics, in the realm of group theory, a class automorphism is an automorphism of a group that sends each element to within its conjugacy class. The class automorphisms form a subgroup of the automorphism group. Some facts: For finite groups, the classical example is a group of order 32 obtained as the semidirect product of the cyclic ring on 8 elements, by its group of units acting via multiplication. Finding a class automorphism in the stability group that is not inner boils down to finding a for the action that is locally a coboundary but is not a global coboundary.

In object-oriented programming, a class is a template that defines the state and behavior common to objects of a certain kind. A class can be defined in terms of other classes. The concept of class hierarchy in computer science is very similar to taxonomy, the classifications of species. The relationships are specified in the science of object-oriented design and object interface standards defined by popular use, language designers (Java, C++, Smalltalk, Visual Prolog) and standards committees for software design like the Object Management Group. The class hierarchy can be as deep as needed. The Instance variables and methods are inherited down through the levels and can be redefined according to the requirement in a subclass. In general, the further down in the hierarchy a class appears, the more specialized its behavior. When a message is sent to an object, it is passed up the inheritance tree starting from the class of the receiving object until a definition is found for the method. This process is called upcasting.

In mathematics, class field theory is the branch of algebraic number theory concerned with the abelian extensions of number fields, global fields of positive characteristic, and local fields. The theory had its origins in the proof of quadratic reciprocity by Gauss at the end of 18th century. These ideas were developed over the next century, giving rise to a set of conjectures by Hilbert that were subsequently proved by Takagi and Artin. These conjectures and their proofs constitute the main body of class field theory. One major result states that, given a number field F, and writing K for the maximal abelian unramifed extension of F, the Galois group of K over F is canonically isomorphic to the ideal class group of F. This statement can be generalized to the Artin reciprocity law; writing CF for the idele class group of F, and taking L to be any finite abelian extension of F, this law gives a canonical isomorphism where denotes the idelic norm map from L to F. This isomorphism is then called the reciprocity map. The existence theorem states that the reciprocity map can be used to give a bijection between the set of abelian extensions of F and the set of closed subgroups of finite index of A standard method for developing global class field theory since the 1930s is to develop local class field theory, which describes abelian extensions of local fields, and then use it to construct global class field theory. This was first done by Artin and Tate using the theory of group cohomology, and in particular by developing the notion of class formations. More recently, Neukrich has found a proof of the main statements of global class field theory without using cohomological ideas. Class field theory also encompasses the explicit construction of maximal abelian extensions of number fields in the few cases where such constructions are known. Currently, this portion of the theory consists of Kronecker-Weber theorem, which can be used to construct the abelian extensions of and the theory of complex multiplication, which can be used to construct the abelian extensions of CM-fields. The Langlands program gives one approach for generalizing class field theory to non-abelian extensions. This generalization is mostly still conjectural. For number fields, class field theory and the results related to the modularity theorem are the only cases known.

In mathematics, especially in the fields of group theory and representation theory of groups, a class function is a function on a group G that is constant on the conjugacy classes of G. In other words, it is invariant under the conjugation map on G. Such functions play a basic role in representation theory.

Critics of the game considered it to be "subversive" and lobbied some stores to remove the product from their shelves, largely unsuccessfully. In the year of its release, Bertell Ollman was interviewed about the game by print and TV news journalists. In 2014, Keith Plocek wrote that the objectives of the game were to "avoid nuclear war and win the revolution". After attracting mainstream media attention during the Cold War, the game went on to sell approximately 230,000 copies. Plocek claims that the game "disappeared" in 1994. A Reddit post circa 2013 piqued limited renewed interest in the game among socialists.

When expected problems with violations of the Armistice with Germany did not eventuate, the Z Reserve was abolished on 31 March 1920. Following the Second World War, a new Z Reserve of soldiers and officers who had served between 3 September 1939 and 31 December 1948 were available for recall if under 45 years of age.

Aztec society traditionally was divided into social classes. The Aztec social classes grew incredibly sophisticated and complex once the Mexican people settled and began to build their empire. It's been said that the class structure was so elaborate that it impressed the Spanish almost as much as the architecture of the empire. The Mexica people, who later became the nucleus of the Aztec empire, were for a time a nomadic tribe looking for a home. As they moved south, they came into contact with advanced peoples. Many cultures of the day looked back to the impressive culture of the Toltecs, and the Aztecs came to admire the Toltec heritage. In fact, eventually the word for artistic creations would be toltecayotl, for the Toltecs, and the Aztecs themselves would claim to be descended from the great Toltec nobles. The Mexicans were anxious to claim a Toltec heritage, so they chose a nobleman of Toltec origin as their first king, a man named Acamapichtli. He fathered a great many children by 20 wives, and his descendants became the heart of a new social class in the empire - the nobles or pipiltin (singular pilli). From then on, a king would always be chosen from among the pipiltin. Basically, the ruling positions were not hereditary, but preference was given to those in the "royal families". Originally the pipiltin status was not hereditary, although the sons of pillis had access to better resources and education, so it was easier for them to become pillis. Later the class system took on hereditary aspects. The nobles had many other privileges. They generally received a fuller education, they were allowed to wear fancier clothes and decorate their houses. They were allowed to hold important government offices. But not all had positions of authority - some were craftsmen, or even palace servants. Those who served with distinction could move up the ranks. The second class were the macehualtin (people), originally peasants. Eduardo Nogueraestimates that in later stages only 20% of the population was dedicated to agriculture and food production. The other 80% of society were warriors, artisans and traders. Slaves or tlacotin also constituted an important class. Aztecs could become slaves because of debts, as a criminal punishment, or as war captives. A slave could have possessions and even own other slaves. Slavery in Aztec society was in some ways more humane than in Western cultures. While some slaves were punished criminals or prisoners of war, others sold themselves or their children into slavery due to economic hardship. Slaves could free themselves by repaying their purchase price. They could marry and own property, and their children were born free. Traveling merchants called pochteca were a small, but important class as they not only facilitated commerce, but also communicated vital information across the empire and beyond its borders. They were often employed as spies.

In mathematics, in the realm of group theory, a class automorphism is an automorphism of a group that sends each element to within its conjugacy class. The class automorphisms form a subgroup of the automorphism group. Some facts:
* Every inner automorphism is a class automorphism.
* Every class automorphism is a and a quotientable automorphism.
* Under a quotient map, class automorphisms go to class automorphisms.
* Every class automorphism is an IA automorphism, that is, it acts as identity on the Abelianization.
* Every class automorphism is a , that is, it fixes all points in the center.
* Normal subgroups are characterized as subgroups invariant under class automorphisms. For infinite groups, an example of a class automorphism that is not inner is the following: take the finitary symmetric group on countably many elements and consider conjugation by an infinitary permutation. This conjugation defines an outer automorphism on the group of finitary permutations. However, for any specific finitary permutation, we can find a finitary permutation whose conjugation has the same effect as this infinitary permutation. This is essentially because the infinitary permutation takes permutations of finite supports to permutations of finite support. For finite groups, the classical example is a group of order 32 obtained as the semidirect product of the cyclic ring on 8 elements, by its group of units acting via multiplication. Finding a class automorphism in the stability group that is not inner boils down to finding a for the action that is locally a coboundary but is not a global coboundary.

CLN is a free library for arbitrary precision arithmetic. It operates on signed integers, rational numbers, floating point numbers, complex numbers, modular numbers, and univariate polynomials. Its implementation programming language is C++. CLN uses object oriented techniques and operator overloading to achieve a natural algebraic syntax: The sum x of two variables a and b is written as x = a + b, as opposed to the function sum(&x, a, b). CLN uses class inheritance to model the natural subsets of the available number types: E.g. the integer class is a subtype of the rational class, just as the integer numbers are a subset of the rational numbers. The complex numbers and all its subtypes behave exactly like the types of numbers known to the Common Lisp language, giving CLN another meaning: it becomes an abbreviation of Common Lisp Numbers. Due to this, CLN can be and is used for implementations of Common Lisp, other interpreted languages, or computer algebra systems. The implementation is efficient. It can be configured to use the GNU Multi-Precision Library as kernel for speed-critical inner loops and implements advanced algorithms like Schönhage–Strassen multiplication, binary splitting and others. All CLN objects are either immediate or reference counted, providing for non-interruptive garbage collection with no burden on the main application.

Class districts (German: Gattungsbezirke) were a classification system for railway goods wagons used by the Deutsche Reichsbahn (1920–1945) in Germany between the wars. After the Deutsche Reichsbahn had been founded in 1920, in 1921 all goods wagons types with the same or similar roles were grouped into so-called class districts. These were named after cities that were the headquarters of a Reichsbahn division or, later, other cities too. Work on re-lettering and renaming the wagons began in 1922 and was largely completed by 1924. Legende:
