A Systematic Framework for Stable and Cost-Efficient Matrix Polynomial Evaluation

J. M. Alonso, J. Sastre, J. Ibáñez +1

A method for evaluating matrix polynomials have recently been developed that require one fewer matrix product ( $1 M$ ) than the Paterson--Stockmeyer (PS) method. Since the computatio…

Commutator estimates for Haar shifts with general measures

Tainara Borges, José M. Conde Alonso, Jill Pipher +1

We study $L^{p} (μ)$ estimates for the commutator $[H, b]$ , where the operator $H$ is a dyadic model of the classical Hilbert transform introduced in \cite{arXiv:2012.10201,arXiv:2212.…
