Resumen de Commutativity of some p -normed algebras with or without involution

A. Ifzarne, Abdellah El Kinani

• The Le Page inequality in a Banach algebra is xy = a yx , for every x, y ? A and some constant a > 0. We examine inequalities of Le Page type in p-Banach algebras with or without involution. As a consequences, some commutativity results are obtained.
