During the Summer of 2009 three students worked with faculty member Eric Egge on problems in combinatorics. Alex Fisher '10 worked on generalizing Stirling number identities to Legendre-Stirling numbers, while Landon Chan '11 and Erin Jones '12 studied functions on Young's lattice which are related to the Bergeron-Garsia nabla operator on symmetric functions. In this picture we see (from left to right) Alex, Erin, and Landon; the blackboard contains some work related to Erin and Landon's project.
