#### Course Description

The subject of enumerative combinatorics deals with counting the number of elements of a finite set. For instance, the number of ways to write a positive integer n as a sum of positive integers, taking order into account, is

For instance, the number of ways to write a positive integer n as a sum of positive integers, taking order into account, is

*2*. We will be concerned primarily with^{n-1}*bijective proofs*, i.e., showing that two sets have the same number of elements by exhibiting a bijection (one-to-one correspondence) between them. This is a subject which requires little mathematical background to reach the frontiers of current research. Students will therefore have the opportunity to do original research. It might be necessary to limit enrollment.## Course Info
