Tensorial and Hadamard Product Inequalities for Selfadjoint Operators in Hilbert Spaces via Two Tominaga s Results

Year: 2025

Type: article

Abstract: In this paper we provide several generalizations for tensorial and Hadamard products of positive linear operators on complex Hilbert spaces of the celebrated scalar inequalities due to Tominaga. They give both multiplicative and additive reverses of Young’s inequality for positive operators in terms of Specht’s ratio and logarithmic mean.
