Instanton sheaves on projective schemes

A h–instanton sheaf on a closed subscheme X of some projective space endowed with an ample and globally generated line bundle OX(h) is coherent whose cohomology table has certain prescribed shape. In this paper we deal sheaves relating them to Ulrich sheaves. Moreover, study smooth curves surfaces, cyclic n–folds, Fano 3–folds scrolls over arbitrary curves. We also family monads associated bundles varieties satisfying mild extra technical conditions.
