On linear morphisms of product spaces (1304.0094v1)
Published 30 Mar 2013 in math.AG
Abstract: Let $\chi$ be a linear morphism of the product of two projective spaces $PG(n,F)$ and $PG(m,F)$ into a projective space. Let $\gamma$ be the Segre embedding of such a product. In this paper we give some sufficient conditions for the existence of an automorphism $\alpha$ of the product space and a linear morphisms of projective spaces $\phi$, such that $\gamma\phi=\alpha\chi$.
