SUMMARY:Algebraic and Enumerative Combinatorics - Tim Miller
CLASS:PUBLIC
DESCRIPTION:TITLE: Vertex models for the product of a Schur and Demazure\np
 olynomial\n\nSPEAKER:\n Tim Miller\n\nAFFILIATION:\n University of Waterlo
 o\n\nLOCATION:\n MC 5479\n\nThere will be a pre-seminar presenting relevan
 t background at the\nbeginning graduate level starting at 1pm.\n\nABSTRACT
 : Demazure atoms and characters are polynomials that each form\na Z-basis 
 for polynomials in n variables. The product of a Schur\npolynomial with a 
 Demazure atom (resp. character) expands into a\nlinear combination of Dema
 zure atoms (resp. characters) with positive\ninteger structure coefficient
 s. There are known combinatorial rules\nthat compute these coefficients us
 ing \"skyline tableaux\" given by\nHaglund\, Luoto\, Mason and Willigenbur
 g. I have found alternative rules\nusing the theory of integrable vertex m
 odels\, inspired by a technique\nintroduced by Zinn-Justin.
