Invariant Hopf 2-Cocycles for Affine Algebraic Groups

We generalize the theory of the second invariant cohomology group H[superscript 2][subscript inv](G) for finite groups G, developed in [3, 4, 14], to the case of affine algebraic groups G, using the methods of [9, 10, 12]. In particular, we show that for connected affine algebraic groups G over an a...
