Hypergeometric sheaves and extraspecial groups in even characteristic

Abstract

We determine precisely which irreducible hypergeometric sheaves have an extraspecial normalizer in characteristic 2 as their geometric monodromy groups. This resolves the last open case of the determination of local monodromy at 0 of irreducible hypergeometric sheaves with finite geometric monodromy group.
