Title: Gaudin subalgebras and stable rational curves.
Date: Tue, Dec 08, 2009, 17:30 - 19:00
Place: Room 002, Mathematical Sciences Building, Komaba Campus
Abstract: We show that Abelian subalgebras of maximal dimensions spanned by
generators of the n-th Kohno-Drinfeld Lie algebra are classified by
the Grothendieck-Knudsen moduli space of stable rational curves with
n+1 marked points. I will explain the relation with Gaudin
integrable systems of statistical mechanics and the representation
theory of the symmetric group in the formulation of Vershik and
Okounkov. The talk is based on joint work with Leonardo Aguirre and
Alexander Veselov.
