In this paper, we will introduce a new Schur-type product for matrices with operator entries, and explore some of its properties. We shall see a connection between this product and the classical Schur product that will allow us to prove that this set

In this paper we study block matrices and multipliers with respect to a Schur-type product operation on them. A subclass of the block Toeplitz matrices is explored, obtaining generalizations of Toeplitz’s and Bennett’s classical theorems that sho

In this paper we analyze the Taylor coefficients of functions in Hardy spaces on the bidisc. We present the two-dimensional versions of some classical Hardy and Paley inequalities and we find certain conditions on the Taylor coefficients for the conv

In this paper, we will consider matrices with entries in the space of operators $\mathcal{B}(H)$, where $H$ is a separable Hilbert space, and consider the class of (left or right) Schur multipliers that can be approached in the multiplier norm by mat

The aim of this paper is to consider operator-valued functions that can be approximated in the strong and weak operator topology by simple functions. We relate these notions with the classical formulations of measurability and provide conditions for

In this paper we characterize Toeplitz matrices with entries in the space of bounded operators on Hilbert spaces $\mathcal{B}(H)$ which define bounded operators acting on $\ell^2(H)$ and use it to get the description of the right Schur multipliers ac
