Wiener pairs of Banach algebras of operator-valued matrices

Abstract

In this article we introduce several new examples of Wiener pairs $\mathcal{A}\subseteq \mathcal{B}$, where $\mathcal{B}=\mathcal{B}({\ell }^2(X;\mathcal{H}))$ is the Banach algebra of bounded operators acting on the Hilbert space-valued Bochner sequence space ${\ell }^2(X;\mathcal{H})$ and $\mathcal{A}=\mathcal{A}(X)$ is a Banach algebra consisting of operator-valued matrices indexed by some relatively separated set $X\subset {\mathbb{R}}^d$. In particular, we introduce $\mathcal{B}(\mathcal{H})$-valued versions of the Jaffard algebra, of certain weighted Schur-type algebras, of Banach algebras which are defined by more general off-diagonal decay conditions than polynomial decay, of weighted versions of the Baskakov-Gohberg-Sjöstrand algebra, and of anisotropic variations of all of these matrix algebras, and show that they are inverse-closed in $\mathcal{B}({\ell }^2(X;\mathcal{H}))$. In addition, we obtain that each of these Banach algebras is symmetric.
