WebWe know that if A ⊆ B, then the cardinality of A is less than that of B. If A and B are finite and the inequality is exact, then the inequality with regard to cardinality is exact as well. So, what happens if we choose A to have cardinality n. Can we have B with cardinality n + 1 but B still being a subset of the continuum? WebCardinality of sets inequality.

The Cardinality of Sumsets: Different Summands

WebThere 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.
