报告摘要：We present some results on the entire solutions for the semilinear biharmonic equation with negative exponent nonlinearity. In particular, the stability outside a compact set of the entire radial solutions will be completely studied, which resolves a remaining case. The second part of the talk concerns the necessary and sufficient conditions for a regular positive entire solution to be a radially symmetric solution. This is based on joint works with X. Huang, W. Long, Z. M. Guo and D. Ye.
报告人简介：周风教授，武汉大学数学系本科毕业，后获法国巴黎第六大学数学博士学位。现为华东师范大学数学科学学院偏微分方程研究中心教授。周风教授迄今在国际著名期刊Comm. Pure Appl. Math., Calc. Var. Partial Differential Equations, J. Funct. Anal., J. Differential Equations等上发表论文四十余篇。其研究领域为非线性偏微分方程。主要感兴趣于研究几何、数学物理中若干非线性偏微分方程解的性态及相关问题，如正则性、多解性、爆破现象、稳定性及解与区域的几何、拓扑特征之间关系等。
