...ed the study of some special kind of monads which were named Horrocks later on (cf. [1] and [5] for example). Monads on projective spaces have been much studied in the past 25 years (see for instance [15, 17, 21, 22] and the references therein). More recently, many authors have also been interested on monads over more general varieties, see [8, 11, 18]. We start the present article in Section 2 studying general m...

... tool in the cohomological characterization of linear and Steiner bundles. We devote Section 4 to the study of linear bundles. Linear bundles on P2 and P3 have been studied since the late 1970’s (cf. [22]), and the mathematical instanton bundles on P2n+1 introduced by Okonek and Spindler in [23] are examples of linear bundles. More general linear monads were first considered in [18]. A cohomological ch...

... hand, hyperplanes and quadrics are the only hypersurfaces in projective space for which there are only a finite number of indecomposable locally-free ACM sheaves, up to twisting by a line bundle (cf. [9]). Some specific varieties have been looked at in the literature; in [3] the authors classify all locally-free ACM sheaves on the grassmannian of lines in P4; certain Fano 3-folds were considered in [4...

...Proof. From Proposition 3.8 we have that if E is the cohomology of the stated monad then (i)-(v) hold because OQn is an ACM sheaf with parameters s = −1 and t = 1 −n and the spinor bundles � are ACM sheaves with parameters s = 0 and t = 1 −n (cf. [ 25, Theorem 2.8 ])....
