报告摘要: In this talk, we will examine several coupled PDE systems that model the interaction between a flow (e.g., gas or fluid) and a structure (e.g., beam or plate). These models arise in many physics and engineering applications. Intuitively, their behavior is governed not only by the constitutive equations (parabolic, hyperbolic, or various damping mechanisms) but also by the boundary conditions, particularly at the interface where the flow meets the structure.

Starting from a canonical heat–wave coupling, we will analyze the underlying semigroups and, in some cases, provide a sharp description of the spectral locations of the generators and their adjoints. Several recent results, as well as open problems, will be introduced. These tools and results will reveal how each component influences the well-posedness and long-time behavior of the coupled system.

报告人简介: 万翔，博士毕业于美国弗吉尼亚大学数学系，师从偏微分方程控制论大师Irena Lasiecka教授。之后于Wayne State University （底特律），George Washington University （华盛顿特区）从事博士后工作。于2022年开始在Loyola University Chicago数学系任教。他的工作主要是偏微分方程相关的控制论，包括平板（plate）方程、流固耦合问题（抛物和双曲）的解的存在性和光滑性，以及边界控制的问题。他的部分工作得到了美国NSF的支持。
