On the equivariant K-theory of the nilpotent cone

Viktor Ostrik

Let G be a simple algebraic group over the complex numbers. Let N be the cone of nilpotent elements in the Lie algebra of G. Let K_{G x C^*}(N) denote the Grothendieck group of the…

Cohomology of subregular tilting modules for small quantum groups

Viktor Ostrik

Let $U$ be the quantum group with divided powers in $l -$ th root of unity and let $u \subset U$ be the Frobenius kernel. V.Ginzburg and S.Kumar proved that the cohomology algebra of…

Dimensions of quantized tilting modules

Viktor Ostrik

Let $U$ be the quantum group with divided powers in $p -$ th root of unity for prime $p$ . For any two-sided cell $A$ in the corresponding affine Weyl group one associates tensor idea…
