Support theory for Drinfeld doubles of some infinitesimal group schemes
Eric M. Friedlander, Cris Negron
Consider a Frobenius kernel G in a split semisimple algebraic group, in very good characteristic. We provide an analysis of support for the Drinfeld center Z(rep(G)) of the represe…

Support Theory for Extended Drinfeld Doubles
Eric M. Friedlander
Following earlier work with Cris Negron on the cohomology of Drinfeld doubles , we develop a "geometric theory" of support varieties for "extended Drinfeld doub…
