The semi-norm

 

The document: Banach space for the theory of the (E) questionBanach space for the theory of the (E) question (270.41 Ko)

This document is a relooked version of an exploration which I started and first published in 2008 under the comic title: BS for ET, in extenso: Banach spaces for the theory of the (E) question. It now has a French matriculation.

With the gravitational term appearing in the covariant version of the Lorentz law in mind, the main topic already was the construction of a C*algebra structure for spaces equipped with a deformed tensor product.

Some technical difficulties concerning the norm was forcing me to look for new roads. My so-called “extrinsic method” found here its first application and came to the rescue; a long time before I got the inspiration for a link with E. B. Christoffel’ work.
