Damping oscillatory Integrals of convex analytic functions

Sanghyuk Lee, Sewook Oh

Let $H \subset R^{d + 1}$ be a compact, convex, analytic hypersurface of finite type with a smooth measure $σ$ on $H$ . Let $κ$ denote the Gaussian curvature on $H$ . We consider the o…

Maximal estimates for averages over degenerate hypersurfaces

Sewook Oh

We study $L^{p}$ boundedness of the maximal average over dilations of a smooth hypersurface $S$ . When the decay rate of the Fourier transform of a measure on $S$ is $1/2$ , we establi…
