Abstract :The Le Page inequality in Banach algebras is \parallel xy \parallel\leqa\parallel yx\parallel. We consider inequalities where a linear involution appears and has consequences on the involution itself and commutativity results.1Keywords : Banach algebra, Commutativity, Cstar-algebra, antilinear map, Spectral radius, Numerical radius.
