Abstract

In this work, we give further refinements of one of the most important extensions to Young’s inequalities due to Alzer–Fonseca–Kovačec (Linear Multilinear Algebra 63(3):622–635, 2015). As applications, we show some related inequalities for operators and some refinements of Young-type inequalities for determinants of positive \(\tau \)-measurable operators.
