报告摘要：In this talk, we introduce maximal functions related to hypersurfaces with vanishing Gaussian curvature in $R^3$. Firstly, we characterize the (p,q)-boundedness of local maximal operators along homogeneous hypersurfaces. Moreover, weighted L^p-estimates are obtained for the corresponding global operators. Secondly, for a class of hypersurfaces that lack a homogeneous structure and pass through the origin, we attempt to look for other geometric properties instead of height of hypersurfaces to characterize the optimal L^p-boundedness of the corresponding global maximal operators. This is a joint work with Dr. Huiju Wang.
