New moduli components of rank 2 bundles on projective space

Abstract

We present a new family of monads whose cohomology is a stable rank two vector bundle on ${\mathbb{P}}^3$. We also study the irreducibility and smoothness together with a geometrical description of some of these families. These facts are used to construct a new infinite series of rational moduli components of stable rank two vector bundles with trivial determinant and growing second Chern class. We also prove that the moduli space of stable rank two vector bundles with trivial determinant and second Chern class equal to 5 has exactly three irreducible rational components.
