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).
