SUMMARY:Seminario IPCTn “Carleman estimates for semi-discrete stochastic parabolic operator and application to controllability”
DESCRIPTION:Abstract: In this talk we consider a semi-discrete forward stochastic parabolic operator with homogeneous Dirichlet conditions in arbitrary dimensions. We show the lack of null controllability for a spatial semi-discretization of a null-controllable stochastic parabolic system from any initial datum. However, by proving a new Carleman estimate for its semi-discrete backward stochastic adjoint system, we achieve a relaxed observability inequality, which is applied to derivative phi-null controllability by duality arguments.\nSpeaker: Ariel Pérez Contreras, Departamento de Ingeniería Matemática, Universidad de Concepción.\nFORMAT: In-person with online streaming\n \n
