Generalized Numerical Radius Inequalities for Schatten p-Norms

Jana Hamza, Hassan Issa

In this paper, we present various inequalities for generalized numerical radius of $2 \times 2$ block matrices for Schatten p-norm. Moreover, we give a refinement of the triangle i…

New applications to combinatorics and invariant matrix norms of an integral representation of natural powers of the numerical values

H. A. Issa, B. Mourad, H. Abbass

Let $\lor^{k} A$ be the $k$ -th symmetric tensor power of $A \in M_{n} (C)$ . In \cite{IAM}, we have expressed the normalized trace of $\lor^{k} A$ as an integral of the $k$ -th power…

The construction of $Ψ^{⋆}$ -algebra by commutator method containing the Bergman projection on the unit ball

Hassan Issa

The manuscript is devoted to the construction of $Ψ^{⋆}$ - algebras containing the Bergman projection on the unit ball $B_{n}$ of $C^{n}$ . We consider the $C^{⋆}$ -algebra $\…
