The Neumann problem for parabolic operators with coefficients satisfying small Carleson condition

Martin Dindoš, Linhan Li, Jill Pipher

In this paper, we resolve the question of whether the Neumann problem for the parabolic PDE on a Lipschitz cylinder $\mathcal O\times\mat…

Localization and interpolation of parabolic Neumann problems

Martin Dindoš, Linhan Li, Jill Pipher

We show a localization estimate for local solutions to the parabolic equation $-\partial_t u+\mbox{div} (A\nabla u)=0$ with zero Neumann data, assuming that the Neumann probl…

The regularity problem for parabolic operators with transversally independent coefficients

Martin Dindoš, Jill Pipher, Martin Ulmer

In this paper, we fully resolve the question of whether the Regularity problem for the parabolic PDE $\partial_tu - \mbox{div}(A\nabla u)=0$ on the domain $\mathbb R^{n+1}_+\times\…

Commutator estimates for Haar shifts with general measures

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

We study estimates for the commutator , where the operator is a dyadic model of the classical Hilbert transform introduced in \cite{arXiv:2012.10201,arXiv:2212.…

An endpoint estimate for product singular integral operators on stratified Lie groups

Michael G. Cowling, Ming-Yi Lee, Ji Li +1

We establish hyperweak boundedness of area functions, square functions, maximal operators and Calderón--Zygmund operators on products of two stratified Lie groups.
