Oscillatory integral operators on manifolds and related Kakeya and Nikodym problems
Song Dai, Liuwei Gong, Shaoming Guo +1
We consider Carleson-Sjölin operators on Riemannian manifolds that arise naturally from the study of Bochner-Riesz problems on manifolds. They are special cases of Hörmander-type o…

Rigidity of the Delaunay triangulations of the plane
Song Dai, Tianqi Wu
We proved a rigidity result for Delaunay triangulations of the plane under Luo's discrete conformal change, extending previous results on hexagonal triangulations. Our result is a…
