泥土谦卑

Introduction, was the culmination of three decades of research on number “aggregates”. Beginning with his paper on the denumerability of infinite sets., published in 1874, Cantor had built a new theory of the infinite. In this theory a collection of objects, even an infinite collection, is conceived of as a single entity.

emulsify

Equality,uivalent under alphabetic change of variable, we intend . to be an abbreviation for. This problem is easily resolved by specifying that . is the first variable an our list . that is distinct from . and from .. Having thereby shown that we can specify a particular formula we will not bother to do so either here or in similar definitions to follow.

IRK

Relational Closure and the Rank Function,ally interested in sets that are transitive. While there exist sets that are not transitive every set has a transitive extension. Indeed, every set has a smallest transitive extension which we call its transitive closure.

accordance

The Fundamental Operations,tially as the union of a sequence of sets .., . ∈ On which were so defined that . ∈ .. iff there exists a wff .(.., .., ..., ..) having no free variables other than .., .., ... , .. and there exist .. , ..., .. ∈ .. such that ..
