报告摘要:
We show that there is a volume gap for nonembedded closed minimal submanifolds in spheres, generalizing Li-Yau’s result for 2 dimension to arbitrary dimension and in particular, proving the Solomon-Yau conjecture for nonembedded case. Besides, for certain minimal CSC hypersurfaces, we also obtain some volume gap results, improving the general gap of Cheng-Li-Yau in these special cases.
