Peter McNamara (Stanford)
will speak on
Factorial Schur Polynomials from the viewpoint of the Six Vertex Model
at 1pm Tuesday 10th August in MLR2
Abstract: The factorial Schur polynomials, also known as double
Schubert polynomials for Grassmannian permutations are a family of polynomials in two alphabets of variables that generalise the
classical Schur functions. Their biggest claim to fame is that they compute the equivariant cohomology of Grassmannians. In this talk, we present the appearance of factorial Schur polynomials combinatorially as the value of a partition function on a well chosen six vertex model from statistical mechanics. This combinatorial approach is suggestive of an underlying phenomenon waiting to be understood. This is joint work with Daniel Bump and Maki Nakasuji.
All welcome.
