报告题目:Structural stability and quasi-neutral limits of subsonic steady-states of Euler-Poisson equations for semiconductors with sonic boundary 报告人:Mei Ming教授 McGill University & Champlain College,Canada 报告时间:2022年11月6日(星期日) 报告地点:ZOOM: 813 1612 3284, Password:221106 报告摘要: In this talk, we review the structure and classification of physic subsonic/supersonic/transonic steady-states for Euler-Poisson equations of semiconductor model with sonic boundary, we are mainly interested in the structural stability and quasi-neutral limits for the subsonic-sonic steady-states. The sonic boundary, a critical case, usually makes the structure of solutions to be various and fantastic, and causes some singularities for the solutions. |
