Vector Bundle construction via Monads on multiprojective Spaces

Algebraic Geometry 2025-05-29 v4

Abstract

In this paper we establish the existence of monads on multiprojective spaces X=P2n+1×P2n+1××P2n+1X=\mathbb{P}^{2n+1}\times\mathbb{P}^{2n+1}\times\cdots\times\mathbb{P}^{2n+1}. We prove stability of the kernel bundle which is a dual of a generalized Schwarzenberger bundle associated to the monads and prove that the cohomology vector bundle is simple, a generalization of instanton bundles. Next we construct monads on Pa1××Pan\mathbb{P}^{a_1}\times\cdots\times\mathbb{P}^{a_n} and prove stability of the kernel bundle and that the cohomology vector bundle is simple. Lastly, we construct the morphisms that establish the existence of monads on P1××P1\mathbb{P}^1\times\cdots\times\mathbb{P}^1.
