Dimension of divergence set of the wave equation

Seheon Ham, Hyerim Ko, Sanghyuk Lee

We consider the Hausdorff dimension of the divergence set on which the pointwise convergence $lim_{t \to 0} e^{i t - Δ} f (x) = f (x)$ fails when $f \in H^{s} (R^{d})$ …

Remarks on estimates for the adjoint restriction operator to curves over the sphere

Seheon Ham, Hyerim Ko, Sanghyuk Lee

Recently, two of the authors obtained estimates for the adjoint restriction operator to finite type curves with respect to general measures. Strikingly, it turns out that some of s…
