Reverses of the Young inequality for matrices and operators
Mojtaba Bakherad, Mario Krnic, Mohammad Sal Moslehian
We present some reverse Young-type inequalities for the Hilbert-Schmidt norm as well as any unitarily invariant norm. Furthermore, we give some inequalities dealing with operator m…
Complementary and refined inequalities of Callebaut inequality for operators
M. Bakherad, M. S. Moslehian
The Callebaut inequality says that \begin{align*} \sum_{ j=1}^n \left(A_j\sharp B_j\right)\leq \left(\sum_{ j=1}^n A_j σB_j\right)\sharp\left(\sum_{ j=1}^n A_j σ^{\bot} B_j\right)\…
Some generalized numerical radius inequalities for Hilbert space operators
Mostafa Sattari, Mohammad Sal Moslehian, Takeaki Yamazaki
We generalize several inequalities involving powers of the numerical radius for product of two operators acting on a Hilbert space. For any suc…
Reverses and variations of Heinz inequality
Mojtaba Bakherad, Mohammad Sal Moslehian
Let be positive definite matrices. We present several reverse Heinz type inequalities, in particular \begin{align*} \|AX+XB\|_2^2+ 2(ν-1) \|AX-XB\|_2^2\leq \|A^ν…
Simple reduced operator crossed products with unique trace
Sanaz Pooya, Shirin Hejazian
In this article we study simplicity and traces of reduced operator crossed products . Given , let be a Powers group, and let…
Exact and approximate operator parallelism
Mohammad Sal Moslehian, Ali Zamani
Extending the notion of parallelism we introduce the concept of approximate parallelism in normed spaces and then substantially restrict ourselves to the setting of Hilbert space o…
