Multihomogeneous Normed Algebras and Polynomial Identities

Leandro Cioletti, José Antônio Freitas, Dimas José Gonçalves

In this paper we consider PI-algebras $A$ over $\mathbb{R}$ or $\C$. It is well known that in general such algebras are not normed algebras. In fact, there is a nilpontent commutative alge…
