Cris Negron, UNC, Cohomology for Drinfeld doubles of finite group schemes
ZoomWe consider a finite group scheme G, and its associated representation category rep G. Here one can think of a finite discrete group, or an infinitesimal group scheme, such as the kernel of the r-th Frobenius map for GL_n over F_p. Via a standard tensor categorical construction one has Drinfeld's center Z(rep G) of the…
