Instanton bundles on Fano threefolds

arXiv:1203.3975 · doi:10.2478/s11533-012-0055-1

Abstract

We introduce the notion of an instanton bundle on a Fano threefold of index 2. For such bundles we give an analogue of a monadic description and discuss the curve of jumping lines. The cases of threefolds of degree 5 and 4 are considered in a greater detail.
