# Algebra Seminar: Panyushev -- Minimal inversion complete sets in Weyl groups and maximal abelian ideals

Dmitri Panyushev (Institute for information transmission problems of the Russian academy
of sciences)

Friday 10 March, 12-1pm, Place: Carslaw 375

Title: Minimal inversion complete sets in Weyl groups and maximal abelian ideals.

Abstract: Let b be a Borel subalgebra of a simple Lie algebra g and W the Weyl group.
In my talk, I explain a relationship between the maximal abelian ideals of b and the
minimal inversion complete sets of W.  The latter have been recently defined by
Malvenuto et al.  (J.  Algebra, 2015).
