报告摘要:A longstanding conjecture on biharmonic submanifolds, proposed by Chen in 1991, is that any biharmonic submanifold in a Euclidean space is minimal. In the case of hypersurfaces, Chen's conjecture was settled the 2 dimensional case by Chen and Jiang around 1987 independently. Hasanis and Vlachos in 1995 settled Chen's conjecture for dimension 3. In collaboration with Hong and Zhan (Adv. Math. 2021), we settled Chen's conjecture for hypersurfaces for dimension 4. More recently, with Hong and Zhan (Trans. AMS 2023), we developed new techniques to settle Chen's conjecture and BMO conjecture on biharmonic hypersurfaces for dimension 5.
