Noncommutative Chebyshev inequality involving the Hadamard product
Mojtaba Bakherad, Silvestru Sever Dragomir
We present several operator extensions of the Chebyshev inequality for Hilbert space operators. The main version deals with the synchronous Hadamard property for Hilbert space oper…
Reverses of Ando's and Hölder-Macarty's inequalities
M. Hajmohamadi, R. Lashkaripour, M. Bakherad
In this paper, we give some reverse-types of Ando's and Hölder-McCarthy's inequalities for positive linear maps, and positive invertible operators. For our purpose, we use a recent…
Further refinements of generalized numerical radius inequalities for Hilbert space operators
Monire Hajmohamadi, Rahmatollah Lashkaripour, Mojtaba Bakherad
In this paper, we show some refinements of generalized numerical radius inequalities involving the Young and Heinz inequalities. In particular, we present \begin{align*} w_{p}^{p}(…
Improvements of Berezin number inequalities
Monire Hajmohamadi, Rahmatollah Lashkaripour, Mojtaba Bakherad
In this paper, we generalize several Berezin number inequalities involving product of operators. For instance, we show that if are positive operators and is any operator…
Interpolating operator Jensen-type inequalities for log-convex and superquadratic functions
Mojtaba Bakherad, Mohsen Kian, Mario Krnic +1
Motivated by some recently established operator Jensen-type inequalities related to a usual convexity, in the present paper we derive several more accurate operator Jensen-type ine…
Berezin number inequalities for Hilbert space operators
Mojtaba Bakherad, Mubariz T. Karaev
In this paper, by using of the definition Berezin symbol, we show some Berezin number inequalities. Among other inequalities, it is shown that if $A, B, X\in{\mathbb{B}}(\mathscr H…
Some Berezin number inequalities for operator matrices
Mojtaba Bakherad
The Berezin symbol of an operator acting on the reproducing kernel Hilbert space over some (non-empty) set is defined by $\wideti…
Some generalized numerical radius inequalities involving Kwong functions
Mojtaba Bakherad
We prove several numerical radius inequalities involving positive semidefinite matrices via the Hadamard product and Kwong functions. Among other inequalities, it is shown that if…
Unitarily invariant norm inequalities involving operators
Mojtaba Bakherad
In this paper, we present some upper bounds for unitarily invariant norms inequalities. Among other inequalities, we show some upper bounds for the Hilbert-Schmidt norm. In particu…
Improvements of some operator inequalities involving positive linear maps via the Kantorovich constant
Leila Nasiri, Mojtaba Bakherad
We present some operator inequalities for positive linear maps that generalize and improve the derived results in some recent years. For instant, if and are positive operat…
