Boğaziçi Üniversitesi Matematik KonuşmalarıHopf-cyclic cohomology of quantum enveloping algebras Serkan Sütlü
Given a coalgebra coextension, we introduce a filtration whose associated spectral
sequence computes the Hochschild cohomology of the coextension. We then use such a spectral
sequence to compute the Hopf-cyclic cohomology of a quantized enveloping algebra of a Lie
algebra. Time permitting, we will also discuss the Hopf-cyclic cohomology of the h-adic Drinfeld-
Jimbo quantum enveloping algebras. (Based on a joint work with A. Kaygun.)
