Rank two bundles on P^n with isolated cohomology
F. Malaspina, A. P. Rao
The purpose of this paper is to study minimal monads associated to a rank two vector bundle on . In particular, we study situations where has…
Horrocks Correspondence on ACM Varieties
F. Malaspina, A. P. Rao
We describe a vector bundle $\sE$ on a smooth -dimensional ACM variety in terms of its cohomological invariants $H^i_*(\sE)$, , and certain graded modules of "…
Horrocks Correspondence on a Quadric Surface
F. Malaspina, A. P. Rao
We extend the Horrocks correspondence between vector bundles and cohomology modules on the projective plane to the product of two projective lines. We introduce a set of invariants…
On codimension two subvarieties in hypersurfaces
N. Mohan Kumar, A. P. Rao, G. V. Ravindra
We show that for a smooth hypersurface $X\subset \bbP^n$ of degree at least 2, there exist arithmetically Cohen-Macaulay (ACM) codimension two subvarieties which are n…
Mathematical Instantons In Characteristic Two
A. P. Rao
On P3, we show that mathematical instantons in characteristic two are unobstructed. We produce upper bounds for the dimension of the moduli space of stable rank two bundles on P3 i…
