Combinatorics Date:  Friday, April 13, 2012 Location:  3866 East Hall (4:10 PM to 5:00 PM) Title:  Flow polytopes and the Kostant partition function Abstract:   This talk will survey the remarkable connections between flow polytopes and Kostant partition functions. One intriguing result in this field is a theorem of Stanley and Postnikov, which expresses the volume of a flow polytope as a Kostant partition function. I'll present a generalization of this theorem, as well as constructions of flow polytopes with combinatorial volumes. The talk is based on joint work with Alejandro H. Morales.
