周五公众报告

报告题目：Large-Time Behavior of Solutions to  1D Compressible Navier-Stokes System in Unbounded Domains with Large Data

报告人：李竞 研究员（中国科学院，杰青）

时间地点：5月11日下午4-5点 后主楼1124

邀请人：许孝精

报告摘要： In this talk, we will report some recent results on the large-time behavior of solutions to the initial and initial boundary value problems with  large initial data for the compressible Navier-Stokes system  describing the  one-dimensional motion of a viscous heat-conducting perfect polytropic  gas in unbounded domains. The temperature is  proved to be  bounded  from below and above independently of both time and space. Moreover, it is shown that the global solution is  asymptotically stable as time tends to infinity. Note that the  initial data can be arbitrarily large. This result is proved by using elementary energy methods.

周五学院公众报告主旨：讲解现代数学中的基本概念、重要结果及其数学思想的起源、方法的创新等，扩展我们的教师和研究生的视野、提高数学修养以及增强学院的学术氛围。邀请各方向的专家用通俗易懂的报告内容、自由互动的讲解方式展现现代数学中重要的基本概念和深刻原理，让听众可以领略到现代数学理论其实是来源于一些大学或研究生阶段就熟知的古典数学中的想法和结论。希望这些报告有助于高年级的本科生、研究生和教师更全面的认识现代数学、享受数学之美。欢迎大家踊跃参与！
