报告人简介:

       窦井波,教授,博士生导师。现为陕西师范大学数学与统计学院教授。研究方向是偏微分方程理论及其应用。近年来与多位合作者集中研究最优几何不等式及其椭圆方程解的存在性等问题。在Adv. Math.,J. Func. Anal.,Inter. Math. Res. Notices, J. Diff. Equ.等国际学术期刊上发表学术论文40余篇;主持国家自然科学基金4项,2019 年获陕西省杰出青年科学基金项目,2022年获陕西高校青年创新团队项目。


摘      要:

       In this talk, we discuss the extremal functions for Onofri inequality in higher dimensional Euclidean space established by del Pino-Dolbeault. To this end, we classify solutions to the n-Liouville equation which is closely related to the Euler-Lagrange equation of the Onofri inequality. By the Serrin-Zou type identity and asymptotic estimates under finite energy, we present an alternative approach to proving the classification results.
