Local rapid stabilization for a Korteweg–de Vries equation with a Neumann boundary control on the right
Jean-Michel Coron,Qi Lü +1 more
TL;DR: In this paper, the authors studied the problem of rapid exponential stabilization for a controlled Korteweg-de Vries equation on a bounded interval with homogeneous Dirichlet boundary conditions and Neumann boundary control.

General Pontryagin-Type Stochastic Maximum Principle and Backward Stochastic Evolution Equations in Infinite Dimensions
TL;DR: In this article, the well-posedness of the vector-valued BSEEs with special data was investigated in the context of the relaxed transposition solutions to the operator-valued vector-values.

Some results on the controllability of forward stochastic heat equations with control on the drift
TL;DR: In this paper, the null/approximate controllability for forward stochastic heat equations with control on the drift was established by a time iteration method and an observability estimate on partial sums of eigenfunctions for elliptic operators.

Fredholm transform and local rapid stabilization for a Kuramoto-Sivashinsky equation
Jean-Michel Coron,Qi Lü +1 more
TL;DR: In this paper, the authors studied the local rapid exponential stabilization problem for a controlled Kuramoto-Sivashinsky equation on a bounded interval, and proposed a feedback control law to force the solution of the closed-loop system to decay exponentially to zero with arbitrarily prescribed decay rates, provided that the initial datum is small enough.

Carleman Estimate for Stochastic Parabolic Equations and Inverse Stochastic Parabolic Problems
TL;DR: In this article, the authors established a global Carleman estimate for stochastic parabolic equations, and solved two inverse problems for the same problem, one is concerned with a determination problem of the history of a stochiastic heat process through the observation at the final time $T, for which they obtained a conditional stability estimate.
