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;\…
Characterizations of smooth spaces by -orthogonality
Mohammad Sal Moslehian, Ali Zamani, Mahdi Dehghani
The aim of this paper is to present some results concerning the -orthogonality in real normed spaces and its preservation by linear operators. Among other things, we prove tha…
Developed Matrix inequalities via Positive Multilinear Mappings
Mahdi Dehghani, Mohsen Kian, Yuki Seo
Utilizing the notion of positive multilinear mappings, we give some matrix inequalities. In particular, Choi--Davis--Jensen and Kantorovich type inequalities including positive mul…
Operator convexity in Krein spaces
M. S. Moslehian, M. Dehghani
We introduce the notion of Krein-operator convexity in the setting of Krein spaces. We present an indefinite version of the Jensen operator inequality on Krein spaces by showing th…
