Categories,sfying certain axioms. Now such a function is a set of ordered pairs whose first components are in . x . and whose second components are in .. This is almost but not quite the same thing as a set of ordered triples of elements of ..

,,opological space, a Hilbert space...) begins: a . consists of a set, together with some extra structure in the form of operations, relations, subsets, sets of subsets, functions to the real numbers, or whatever. Also, as we will see, these operations, relations, etc. are themselves special kinds of

Ordinal numbers, use this process of succession to define the natural numbers - to do God’s work, in Kronecker’s phrase - starting from nothing (more precisely, the empty set) and progressing from one number to the next. As succession is the defining characteristic of natural numbers, so induction is the key proof

Axiomatic set theory,The axiom whose status is least clear is the Axiom of Choice. As a result, it has received special attention from mathematicians, and consequences of its truth or falsity have been noted in various parts of mathematics. We will consider some of these. We also develop a theory of infinite cardinal nu

Categories,ered pairs with certain properties. Natural numbers are particular sets, and from them the standard number systems of mathematics can be developed in familiar ways. More abstractly, a group is an ordered pair whose first element is a set . and whose second element is a function from . x . to ., sati
