Abstract

In this article we present new proofs for the boundedness and the compactness on 2\ell^2 of the Rhaly matrices, also known as terraced matrices. We completely characterize when such matrices belong to the Schatten class Sq(2)\mathcal{S}^q(\ell^2), for 1<q<1<q<\infty. Finally, we apply our results to study the Hadamard multipliers in weighted Dirichlet spaces, answering a question left open by Mashreghi-Ransford.
