CalTitle1: Algebra Seminar: On some generalizations of Soergel categories in small ranks

Auth: kevinc@pkevinc.pc (assumed)

Thomas Gobet (University of Sydney) Friday 1 June, 12-1pm, Place: Carslaw 375 Title: On some generalizations of Soergel categories in small ranks Abstract: We describe the split Grothendieck ring of an extended category of Soergel bimodules attached to a Coxeter group of type A_2, obtained by taking one generator per reflection. This gives rise to an algebra which is a quotient of the corresponding affine Hecke algebra, and contains the (spherical) Hecke algebra of type A_2 as a subalgebra. We also sketch the construction of a category which is defined in a similar way as Soergel’s one, attached to a complex reflection group of rank one. This is joint work with Anne-Laure Thiel.
