Controllability for semi-discrete semilinear stochastic parabolic operators
Rodrigo Lecaros, Ariel A. Pérez, Manuel F. Prado
In \cite{LPP:2025}, it was shown that, in arbitrary dimension, the spatial semi-discretization of a controlled stochastic parabolic operator is generically not null-controllable. N…

Inverse Random Source and Cauchy Problems for Semi-Discrete Stochastic Parabolic Equations in Arbitrary Dimensions
Rodrigo Lecaros, Ariel A. Pérez, Manuel F. Prado
In this paper, we study two types of inverse problems for space semi-discrete stochastic parabolic equations in arbitrary dimensions. The first problem concerns a semi-discrete inv…

Carleman estimate for semi-discrete stochastic parabolic operators in arbitrary dimension and applications to controllability
Rodrigo Lecaros, Ariel A. Pérez, Manuel F. Prado
This paper considers a semi-discrete forward stochastic parabolic operator with homogeneous Dirichlet conditions in arbitrary dimensions. We show the lack of null controllability f…
