Hermite–Hadamard inequalities and their refinements have been investigated for a long
period of time. In this paper, we obtained refinements of the Hermite–Hadamard inequality of …

The main focus of this paper is on establishing inequalities for the norm and numerical
radius of various operators applied to a power series with the complex coefficients h (λ)=∑ …

The Berezin transform A and the Berezin radius of an operator A on the reproducing kernel
Hilbert space over some set Ω with normalized reproducing kernel̂kλ are defined …

In the literature, there are many criteria to generalize the concept of a numerical radius; one
of the most recent and interesting generalizations is the so-called generalized Euclidean …
