报告题目:Inverse Problem and Scientific Computing IV

报告人:杨家青 教授(西安交通大学)

报告时间:2023年12月12日 09:30-10:30

报告地点:理学楼A110

摘要:In this talk, I will report an inverse scattering problem of determining a penetrable obstacle with a conductivity boundary condition. By analyzing the Lp solvability of the scattering model and illustrating in detail the singularity of the solution near the interface, we show that the penetrable obstacle can be uniquely determined by the fixed frequency far-field measurements, ignoring its contents. Furthermore, we also show that part information of the physical coefficients can be uniquely determined at the interface from the same measurements.

 

报告人介绍:杨家青,西安交通大学教授. 研究方向为反问题的数学理论与计算方法,主要包括波的散射与反散射、流体力学方程反问题、偏微分方程反问题的一般理论等.SIAPSINUMSISCSIIMSIPJCPJDE等国际期刊发表学术论文近四十篇。分别主持国家自然科学基金优秀青年基金一项与国家重点研发计划课题一项;获得中国工业与应用数学学会应用数学青年科技奖、陕西省百人计划青年项目等。
