微分动力系统报告报告题目: Ergodic theory for vector fields with singularities报告人:杨大伟 (苏州大学)时间:2021-11-30 13:30-14:30腾讯会议ID: 417-262-031摘要:We study vector fields with singularities from the viewpoint of ergodic theory. One important prototype is the Lorenz attractor. Theoretical notions for the weak hyperbolicity of vector fields with singularites include singular hyperb...
微分动力系统报告报告题目: Stability of the stochastic Ginzburg-Laudau systems报告人:郑言 (国防科技大学)时间:2021-11-29 10:00-11:00腾讯会议ID: 590-638-674 摘要:This talk is concerned with the 3D stochastic Ginzburg-Landau equation with degenerate random forcing. We establish the stability of stochastic systems by investigating the relationship between invariant measures under the action o...
