There are two approaches to cardinality: one which compares sets directly using bijections and injections, and another which uses cardinal numbers. The cardinality of a set is also called its size, when no confusion with other notions of size is possible. See more In mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set $${\displaystyle A=\{2,4,6\}}$$ contains 3 elements, and therefore $${\displaystyle A}$$ has a cardinality of 3. … See more While the cardinality of a finite set is just the number of its elements, extending the notion to infinite sets usually starts with defining the notion of comparison of arbitrary sets (some of which are possibly infinite). Definition 1: A = B See more If the axiom of choice holds, the law of trichotomy holds for cardinality. Thus we can make the following definitions: • Any set X with cardinality less than that of the natural numbers, or X < N , is said to be a finite set. • Any set X that has the same cardinality as … See more • If X = {a, b, c} and Y = {apples, oranges, peaches}, where a, b, and c are distinct, then X = Y because { (a, apples), (b, oranges), (c, … See more A crude sense of cardinality, an awareness that groups of things or events compare with other groups by containing more, fewer, or the same number of instances, is observed in a variety of present-day animal species, suggesting an origin millions of … See more In the above section, "cardinality" of a set was defined functionally. In other words, it was not defined as a specific object itself. However, such an … See more Our intuition gained from finite sets breaks down when dealing with infinite sets. In the late nineteenth century Georg Cantor, Gottlob Frege, Richard Dedekind and others rejected the view that the whole cannot be the same size as the part. One example of this is See more
