Geometry, Combinatorics and Integrable Systems Seminar - Leonardo Mihalcea
Title: Cotangent Schubert Calculus
Speaker: Leonardo Mihalcea, Virginia Tech
Abstract: A natural question with roots in representation theory and microlocal analysis is to find good analogues of Schubert classes in the intersection rings of the cotangent bundle of a flag manifold. One answer is given in terms of the characteristic classes of singular subvarieties in the flag manifold, such as the Chern-Schwartz-MacPherson classes (in cohomology) or motivic Chern classes (in K theory). I will give the definition of these classes, and I will discuss some (known or conjectural) properties of the transition matrix to the ordinary Schubert basis. Joint work with P. Aluffi, J. Schurmann, C. Su.
