Tensorization of $p$-weak differentiable structures

Differential Geometry 2022-06-13 v1 Metric Geometry

Abstract

We consider pp-weak differentiable structures that were recently introduced by the first and last named authors, and prove that the product of pp-weak charts is a pp-weak chart. This implies that the product of two spaces with a pp-weak differentiable structure also admits a pp-weak differentiable structure. We make partial progress on the tensorization problem of Sobolev spaces by showing an isometric embedding result. Further, we establish tensorization when one of the factors is PI.
