Comultiplications. Exponentials. Deformations

Abstract

Completely different notions are now expounded: first comultiplications and interior multiplications; then exponentials (defined without exponential series); finally deformations of Clifford algebras, which need both exponentials and interior products. Exterior algebras play an important role, because with a weak additional hypothesis (the existence of scalar products) we shall prove that Clifford algebras are isomorphic to them as K-modules (and even as comodules). The first two sections of Chapter 3 are sufficient prerequisites for almost all this chapter.
