چکیده
Abstract. This paper presents a new observability estimate for parabolic equations in × (0, T ), where is a convex domain. The observation region is restricted over a product set of an open nonempty subset of and a subset of positive measure in (0, T ). This estimate is derived with the aid of a quantitative unique continuation at one point in time. Applications to the bang-bang property for norm and time optimal control problems are provided.

An observability for parabolic equations from a measurable set in time
This paper presents a new observability estimate for parabolic equations in Ω × (0, T ), where Ω is a convex domain.

متن کاملCarleman estimates and observability inequalities for parabolic equations with interior degeneracy
We consider a parabolic problem with degeneracy in the interior of the spatial domain, and we focus on Carleman estimates for the associated adjoint problem. The novelty of interior degeneracy does not let us adapt previous Carleman estimate to our situation. As an application, observability inequalities are established.
متن کاملCarleman estimates for semi-discrete parabolic operators and application to the controllability of semi-linear semi-discrete parabolic equations
In arbitrary dimension, in the discrete setting of finite-differences we prove a Carleman estimate for a semi-discrete parabolic operator, in which the large parameter is connected to the mesh size. This estimate is applied for the derivation of a (relaxed) observability estimate, that yield some controlability results for semi-linear semi-discrete parabilic equations. Sub-linear and super-line...
متن کاملParameter determination in a parabolic inverse problem in general dimensions
It is well known that the parabolic partial differential equations in two or more space dimensions with overspecified boundary data, feature in the mathematical modeling of many phenomena. In this article, an inverse problem of determining an unknown time-dependent source term of a parabolic equation in general dimensions is considered. Employing some transformations, we change the inverse prob...
