Jörg Schürmann (Münster) Title: (Degenerate) affine Hecke algebras and (motivic) Chern classes of Schubert cells Abstract: We explain in the context of complete flag varieties X=G/B the relation between (motivic) Chern classes of Schubert cells and convolution actions of (degenerate) affine Hecke-algebras as in the work of Ginzburg and Tanisaki. This is joint work with P. Aluffi, L. Mihalcea and C. Su.
