Inclusion-exclusion principle in homological algebra

Algebra & Discrete Mathematics

Speaker: Anton Khoroshkin, Stony Brook
Location: 0 MSB
Start time: Tue, Apr 3 2012, 4:10PM

I will explain how one can use the inclusion-exclusion principle to construct free resolutions of monomial objects in different algebraic settings. The appropriate theory of Grobner bases allows to extend these resolutions to the general situation. Particular examples include associative algebras, commutative algebras, operads and even enumerative problems in pattern avoidance.

This is a special joint seminar with the String Theory group, please note the special time.
