February 21, 2009 – Alan Davis – Combinatorics

We are very fortunate to have Alan Davis talk about combinatorics on February 21, 2009. His talk about combinatorics will include the following topics: Counting permutations and combinations, counting with repetition, binomial coefficients, Pascal’s triangle, Pascal’s identity, Vandermonde’s identity, and the inclusion-exclusion principle.
Combinatorics is related to many other areas of mathematics such as algebra, probability, and geometry, and also computer science and statistics. More information about this interesting branch of mathematics can be found here.
