Endpoint estimates for maximal operators associated to the wave equation

Chu-Hee Cho, Sanghyuk Lee, Wenjuan Li

We consider the -- maximal estimates associated to the wave operator \begin{equation*} e^{ it\sqrt{-Δ}}f(x) = \frac{1}{(2π)^d}\int_{\mathbb{R}^d} e^{i(x \cdot ξ\, +…

Bourgain's counterexample in the sequential convergence problem for the Schrödinger equation

Chu-Hee Cho, Daniel Eceizabarrena

We study the problem of pointwise convegence for the Schrödinger operator on along time sequences. We show that the sharp counterexample to the sequential Schröding…
