2025年03月19日上午，美国布朗大学舒其望教授应国家数学与交叉科学中心邀请做客综合论坛，并做了题为“数值边界条件的Inverse Lax-Wendroff方法”的学术报告。报告由郑伟英研究员主持，40多位师生参加了本次报告会，袁亚湘院士为舒其望教授颁发了杰出讲座证书。

本次演讲舒其望教授详细讨论了一类高阶有限差分格式的数值边界条件处理算法，用于使用笛卡尔网格求解复杂几何上的双曲 Hamilton-Jacobi 方程、双曲守恒定律和对流-扩散方程。 挑战源于边界可能与网格不匹配以及如何构造内部高阶格式在边界外虚拟点值，保证格式的稳定性方案的宽模板以及边界可能与网格不对齐的事实。 舒其望教授的报告十分精彩，具有很强的引领性和指导性。与会师生分别就自己研究中遇到的相关问题与舒其望教授展开了热烈的讨论，对大家的问题，舒教授都作了精彩的解答。

个人介绍：Chi-Wang Shu obtained his BS degree from the University of Science and Technology of China in 1982 and his PhD degree from UCLA in 1986. He has been at Brown University since 1987, where he was the Chair of the Division of Applied Mathematics between 1999 and 2005, and is now the Theodore B. Stowell University Professor of Applied Mathematics. His research interest includes high order numerical methods for solving hyperbolic and other convection dominated PDEs, with applications in CFD and other areas. He is the Chief Editor of Journal of Scientific Computing and of Communications on Applied Mathematics and Computation, and serves in the editorial boards of several other journals including Journal of Computational Physics, Mathematics of Computation and Science China Mathematics. He is a SIAM Fellow, an AMS Fellow and an AWM Fellow, and an invited 45-minute speaker in the International Congress of Mathematicians (ICM) in 2014. He received the First Feng Kang Prize of Scientific Computing in 1995, the SIAM/ACM Prize in Computational Science and Engineering in 2007, and the SIAM John von Neumann Prize in 2021.
