Multi-scale sparse domination
David Beltran, Joris Roos, Andreas Seeger
We prove a bilinear form sparse domination theorem that applies to many multi-scale operators beyond Calderón-Zygmund theory, and also establish necessary conditions. Among the ap…

Endpoint sparse domination for classes of multiplier transformations
David Beltran, Joris Roos, Andreas Seeger
We prove endpoint results for sparse domination of translation invariant multiscale operators. The results are formulated in terms of dilation invariant classes of Fourier multipli…
