»ã±¨ÌáÒª£ºLet M be an n-dimensional compact Riemann manifold. We study an oscillatory operator and obtain its maximal estimate on Lp and Hp. Particularly, we obtain the sharp estimate on L1 case and Hp case for p less than 1. As an application, we obtain the almost everywhere convergence and approximation property. This is a joint work with Jiecheng Chen, ziyao Liu and Fayou Zhao.
