[Banach] Abstract of a paper by Jorge Tomas Rodriguez

This is an announcement for the paper "On the norm of products of polynomials on ultraproduct of Banach spaces" by Jorge Tomas Rodriguez.

Abstract: The purpose of this article is to study the problem of finding sharp lower bounds for the norm of the product of polynomials in the ultraproducts of Banach spaces $(X_i)_{\mathfrak U}$. We show that, under certain hypotheses, there is a strong relation between this problem and the same problem for the spaces $X_i$.
