Wavelet resolution and Sobolev regularity of Calderón-Zygmund operators on domains
Francesco Di Plinio, A. Walton Green, Brett D. Wick
Given a uniform domain , we resolve each element of a suitably defined class of Calderòn-Zygmund (CZ) singular integrals on as the linear combination of…

Invertibility of Positive Toeplitz Operators and Associated Uncertainty Principle
A. Walton Green, Mishko Mitkovski
We study invertibility and compactness of positive Toeplitz operators associated to a continuous Parseval frame on a Hilbert space. As applications, we characterize compactness of…
