We prove that the Drinfeld double of an arbitrary finite group scheme has finitely generated cohomology. That is to say, forGany finite group scheme, andD(G) the Drinfeld double of the group ringkG, we show that the self-extension algebra of the trivial representation forD(G) is a finitely generated algebra, and that for eachD(G)-representationVthe extensions from the trivial representation toVform a finitely generated module over the aforementioned algebra. As a corollary, we find that all categoriesdual toare also of finite type (i.e. have finitely generated cohomology), and we provide a uniform bound on their Krull dimensions. This paper completes earlier work of Friedlander and the author.
