A and B have the same cardinality if it's possible to match each element of A to a different element of B in such a way that every element of both sets is matched exactly once.
1) Two finite countable sets are not necessarily of the same cardinality 2) Every two denumerable sets are of the same cardinality.Set A is denumerable if there is a bijection f:N->A ---How to construct a surjection f:N->S? Also the inverse of function f which is g:S...
Here κ is the vertex connectivity of G and α is the cardinality of a largest set of independent vertices of G. In another paper Chvátal points out that the proof of this result is in fact a polynomial time construction that either produces a Hamilton cycle or a set of more than κ ...

Given a set S we denote by |S| the cardinality of the set S. We say that two, S1 and S2 sets have the same cardinality, or |S1|=|S2|, if there is a bijection b between the sets S1 and S2, b:S1→S2 Answer and Explanation: ...
Define for a, b > 0 , the set aS + b = {ax + b : x \in S} Prove that sup(aS + b) = a sup(S) + b and inf(aS + b) = a inf(S) + b . How do you prove two sets have the same cardinality? How to prove that the closure of a set is ...
