Determining of unknown functions of different arguments in minor coefficient and right-hand side of semilinear ultraparabolic equation

Karpatsʹkì Matematičnì Publìkacìï, 2020
In this paper, we consider the inverse problem for semilinear ultraparabolic equation. The equation has two unknown functions of different arguments in its minor coefficient and in right-hand side function.

An anisotropic inverse boundary value problem [PDF]

Communications on Pure and Applied Mathematics, 1990
AbstractWe consider the impedance tomography problem for anisotropic conductivities. Given a bounded region Ω in space, a diffeomorphism Ψ from Ω to itself which restricts to the identity on ∂ Ω, and a conductivity γ on Ω, it is easy to construct a new conductivity Ψ*γ which will produce the same voltage and current measurements on ∂ Ω.We prove the ...

On an inverse boundary value problem [PDF]

Computational & Applied Mathematics, 2006
This paper is a reprint of the original work by A. P. Calderon published by the Brazilian Mathematical Society (SBM) in ATAS of SBM (Rio de Janeiro), pp. 65-73, 1980. The original paper had no abstract, so this reprint to be truthful to the original work is published with no abstract.
