O QUE SIGNIFICA PROPER CLASS EM INGLÊS

Classe (teoria do conjunto)

Class (set theory)

Na teoria dos setores e suas aplicações ao longo da matemática, uma classe é uma coleção de conjuntos que podem ser inequivocamente definidos por uma propriedade que todos os seus membros compartilham. A definição precisa de "classe" depende do contexto fundacional. No trabalho sobre a teoria dos setores de Zermelo-Fraenkel, a noção de classe é informal, ao passo que outras teorias definidas, como a teoria do conjunto de Von Neumann-Bernays-Gödel, axiomatizam a noção de "classe apropriada", por exemplo, como entidades que não são membros de outra entidade. Uma classe que não é um conjunto é chamada de classe apropriada, e uma classe que é um conjunto às vezes é chamada de classe pequena. Por exemplo, a classe de todos os números ordinais e a classe de todos os conjuntos são classes apropriadas em muitos sistemas formais. Fora da teoria do conjunto, a palavra "classe" às ​​vezes é usada de forma sinônima com "set". Este uso data de um período histórico onde classes e conjuntos não foram distinguidos como estão na moderna terminologia teórica. Muitas discussões de "classes" no século XIX e anteriores realmente se referem a conjuntos, ou talvez a um conceito mais ambíguo.

In set theory and its applications throughout mathematics, a class is a collection of sets that can be unambiguously defined by a property that all its members share. The precise definition of "class" depends on foundational context. In work on Zermelo–Fraenkel set theory, the notion of class is informal, whereas other set theories, such as Von Neumann–Bernays–Gödel set theory, axiomatize the notion of "proper class", e.g., as entities that are not members of another entity. A class that is not a set is called a proper class, and a class that is a set is sometimes called a small class. For instance, the class of all ordinal numbers, and the class of all sets, are proper classes in many formal systems. Outside set theory, the word "class" is sometimes used synonymously with "set". This usage dates from a historical period where classes and sets were not distinguished as they are in modern set-theoretic terminology. Many discussions of "classes" in the 19th century and earlier are really referring to sets, or perhaps to a more ambiguous concept.

A class that is not a set is called a proper class. Intuitively the distinction between sets and proper classes is not too clear. Roughly speaking a set is a "small" class and a proper class is exceptionally "large." The axiom of class formation ...

More Precisely: The Math You Need to Do Philosophy

We turn to a more general theory of collections. According to class theory, all collections are classes. Any class is either a set or else a proper class. Every set is a class, but not all classes are sets. Specifically, the proper classes are not sets .

Discovering Modern Set Theory: The basics

... at any moment in set- theoretic time, there is some x E X that has not yet been constructed. Therefore, in particular, if at least one of X, Y is a proper class, then the pair (X, Y) could not have been formed at any moment in set-theoretic history.

Foundations of Mathematical Logic

... or the class of all ideas, are members of themselves. Now let R (the Russell class) be the class of all proper classes. If R is a proper class, then, since R is the class of all such classes, R is a member of R, and hence R is not a proper class.
