Surfaces generating the even primal cohomology of an abelian fivefold

Jonathan Conder, Edward Dewey, Elham Izadi

Given a very general abelian fivefold $A$ and a principal polarization $Θ \subset A$ , we construct surfaces generating the algebraic part of the middle cohomology $H^4(Θ, {\mathbb Q…

Residues in group completions and the Cech cohomology of BG

Edward Dewey

Let $G$ be a connected affine algebraic group over $C$ , $G \to X$ be an open immersion of $G$ -varieties, $Z = X - G$ and $i : Z \to X$ be the inclusion. Let $α\in H^*(G,\math…

Characteristic Classes of Cameral Covers

Edward Dewey

We study the stack M of cameral covers for a complex reductive group G, introduced by Donagi and Gaitsgory. We compute its rational cohomology ring. In the special case G=GL(n), M…
