Another remark on a result of Ding-Jost-Li-Wang
Let be a compact Riemann surface, be a positive smooth function
on . It is well known the functional achieves its minimum under
Ding-Jost-Li-Wang condition. This result was generalized to nonnegative by
Yang and the author. Later, Sun and Zhu (arXiv:2012.12840) showed
Ding-Jost-Li-Wang condition is also sufficient for achieves its minimum
when changes sign, which was reproved later by Wang and Yang (J. Funct.
Anal. 282: Paper No. 109449, 2022) and Li and Xu (Calc. Var. 61: Paper No. 143,
2022) respectively using flow approach. The aim of this note is to give a new
proof of Sun and Zhu's result. Our proof is based on the variational method and
the maximum principle.Comment: 13 pages. To appear on Proc. AM
