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