Observability Problem for Some Stochastic Partial Differential Equations

Abstract 

Observability problem is one of the fundamental problems in control theory. On the other hand, it relates to the unique continuation problem for the equations which describe the control systems. In this talk, we survey some recent progress on the observability problem for control systems governed by some typical stochastic partial differential equations.
