Matricial Radius: A Relation of Numerical radius with Matricial Range
Mohsen Kian, Mahdi Dehghani, Mostafa Sattari
It has been shown that if is a complex matrix, then {\small\begin{align*} ω(T)&=\frac{1}{n}\sup\left\{|\mathrm{Tr}\ X|;\ X\in W^n(T)\right\}\\ &=\frac{1}{n}\sup\left\{\|X\|_1;\…
Variants of Ando--Hiai type inequalities for deformed means and applications
Mohsen Kian, M. S. Moslehian, Yuki Seo
For an -tuple of positive invertible operators on a Hilbert space, we present some variants of Ando--Hiai type inequalities for deformed means from an -variable operator mean…
Positivity of block matrices of operators
Mohammad Sal Moslehian, Mohsen Kian, Qingxiang Xu
We review some of the significant generalizations and applications of the celebrated Douglas theorem on the equivalence of factorization, range inclusion, and majorization of opera…
