New bounds for Stein's square functions in higher dimensions

Shengwen Gan, Changkeun Oh, Shukun Wu

We improve the $L^{p} (R^{n})$ bounds on Stein's square function to the best-known range of the Fourier restriction problem when $n \geq 4$ . Applications including certain local…

A note on local smoothing estimates for fractional Schrödinger equations

Shengwen Gan, Changkeun Oh, Shukun Wu

We improve local smoothing estimates for fractional Schrödinger equations for $α \in (0, 1) \cup (1, \infty)$ .

The Bochner-Riesz problem: an old approach revisited

Shaoming Guo, Changkeun Oh, Hong Wang +2

We show that the recent techniques developed to study the Fourier restriction problem apply equally well to the Bochner-Riesz problem. This is achieved via applying a pseudo-confor…

Changkeun Oh

We obtain a sharp bilinear restriction estimate for the paraboloid in $R^{3}$ for $q > 3.25$ .
