Large rank simple bundles of all homological dimensions

Algebraic Geometry 2023-12-22 v2

Abstract

For n3n\geq 3 and rnr\geq n, we show that there are rank-rr vector bundles on Pn\mathbb{P}^n with arbitrary homological dimension. We apply the Bernstein-Gel'fand-Gel'fand correspondence to translate the vector bundle question into a problem on modules over the exterior algebra. Then, we use linear algebra to construct the desired modules.
