Cohomology for Drinfeld doubles of some infinitesimal group schemes
Eric Friedlander, Cris Negron
Consider a field k of characteristic p > 0, G_r the r-th Frobenius kernel of a smooth algebraic group G, DG_r the Drinfeld double of G_r, and M a finite dimensional DG_r-module. We…

Twists of quantum Borel algebras
Cris Negron
We classify Drinfeld twists for the quantum Borel subalgebra u_q(b) in the Frobenius-Lusztig kernel u_q(g), where g is a simple Lie algebra over C and q an odd root of unity. More…

Small quantum groups associated to Belavin-Drinfeld triples
Cris Negron
For a simple Lie algebra L of type A, D, E we show that any Belavin-Drinfeld triple on the Dynkin diagram of L produces a collection of Drinfeld twists for Lusztig's small quantum…
