Abstract

In this paper we find the explicit form for the equalizing term in the inequality related to Landau–Grüss inequality for elementary operators, which enabled us to refine inequalities related to operator Landau–Grüss norm inequalities for p-modifications of initarily invariant norms. Specially, for Schatten p-norms with \(p\ge 2\) those inequalities have additionally simplified form, which enables, among others, to analyze equality cases in considered operator inequalities. A broader family of mixed norms inequalities related to the operator Landau–Grüss inequality is also presented.
