In algebraic geometry, a branch of mathematics, the Horrocks-Mumford bundle is an indecomposable rank 2 vector bundle on 4-dimensional projective space P⁴. It is the only such bundle known, although a generalized construction involving Paley graphs produces other rank 2 sheaves (Sasukara et al 1993). The zero sets of sections of the Horrocks-Mumford bundle are abelian surfaces of degree 10, called Horrocks-Mumford surfaces.
