Lipschitz stability for linear parabolic systems with interior degeneracy

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we study an inverse problem for linear degenerate parabolic systems with one force. We establish Lipschitz stability for the source term from measurements of one component of the solution at a positive time and on a subset of the ...

Reachability of a second-order integro-differential equation on Riemannian manifold for a viscoelasticity model

open access: yesElectronic Journal of Differential Equations, 2019
We study a reachability problem for a second-order integro-differential equation on a finite-dimensional Riemannian manifold, which is a model equation for viscoelasiticity.

Conditional stability of a solution of a difference scheme for an ill-posed Cauchy problem

open access: yesElectronic Journal of Differential Equations, 2018
In this article, we obtain criteria for stability of two-layer difference schemes for an abstract ill-posed Cauchy problem. Method of proof is based on obtaining a priori difference weighted Carleman type estimates.

Null controllability for linear parabolic cascade systems with interior degeneracy

open access: yesElectronic Journal of Differential Equations, 2016
We study the null controllability problem for linear degenerate parabolic systems with one control force through Carleman estimates for the associated adjoint problem.

Uniqueness results for variable coefficient Schrödinger equations

open access: yesBruno Pini Mathematical Analysis Seminar
In this note we shall present some result proved in [16] on the uniqueness of Schrödinger equations with space-variable coefficients, that is Schrödinger equations where the Laplacian is replaced by an elliptic operator with space-variable coefficients.

Carleman Type Estimates in an Anisotropic Case and Applications

open access: yesJournal of Differential Equations, 1993
We give proofs and some further applications of estimates announced in the author's note [Sov. Math. Dokl. 22, 639-642 (1980); transl. from Dokl. Akad. Nauk SSSR 255, 18-21 (1980; Zbl 0468.35030)]. These results extend those of \textit{L. Hörmander} [Linear partial differential operators, Springer, Berlin etc.
