报告人简介:

         丁冰冰，南京师范大学数学科学学院副教授、硕士生导师。主要从事非线性偏微分方程组的理论研究，重点关注高维非线性波动方程（组）的解的适定性问题。近期在Adv. Math.、SIAM J. Math. Anal.、J. Differential Equations等国际知名学术杂志发表论文多篇，主持非线性高维双曲方程解性质相关科研项目，从事非线性偏微分方程领域研究，努力推动该领域的学术交流与发展。

摘      要：

        In this talk, I will focus on the blow-up result for three-dimensional (3-D) steady supersonic flow with a class of large data (specifically, short-pulse data). By imposing an additional first-order compatibility condition with respect to the outgoing direction, we are able to determine the precise blow-up point and demonstrate that shock will form at this location.

This is a joint work with Prof. Zhouping Xin and Prof. Huicheng Yin.

          欢迎老师、同学们参加、交流！
