Abstract：We start with the proof of a generalized Obata theorem on a compact manifold with boundary studied by Escobar (CPAM 90). This gives a natural motivation of the study of a Han-Li conjecture. Next we will mention our recent advance on this conjecture. Finally, we (joint with Mr. Yuping Ruan, an undergraduate student at nju) announce an improvement of Jin-Xiong's 2017 work, involving a conjecture of an isoperimetric inequality over scalar flat conformal class.
