On the compactness of bi-parameter singular integrals
Cody B. Stockdale, Cody Waters
We establish a new theorem for the compactness of bi-parameter Calderón-Zygmund singular integral operators. Namely, we show that if a bi-parameter CZO satisfies the produ…

Compact pseudodifferential and Fourier integral operators via localization
Cody B. Stockdale, Cody Waters
We present a general framework of localized operators, i.e., operators whose matrix coefficients with respect to the Gabor frame are concentrated on the diagonal. We show that loca…
