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).
