报 告 人：柳絮教授（东北师范大学数学与统计学院）
In this talk, thecontrollability and observability for some coupled stochastic parabolic systemsare studied, respectively, through one control and observer. The methods arebased on the Lebeau-Robbiano strategy and Carleman estimate method. Compared todeterministic coupled parabolic systems, the coupling appearing in diffusionterms in the stochastic case introduces a new phenomena. A counterexample ispresented to show that the controllability of coupled stochastic parabolicsystems is not robust with respect to the coupling coefficient in diffusionterms.
