ON THE METHOD FOR RECONSTRUCTING THE BOUNDARY CONDITION FOR PARABOLIC LINEAR EQUATIONS
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2020 Background. A problem of determination of unknown boundary condition often appears in different fields of physics and technical sciences in cases when direct measuring of field characteristics at some part of the boundary is difficult or even ...

The Numerical Solution of an Inverse Pseudoparabolic Problem with a Boundary Integral Observation
MathematicsDirect and inverse problems for a pseudoparabolic equation are considered. The direct (forward) problem is to find the solution of the corresponding initial–boundary-value problem for known model parameters, as well as the initial and boundary conditions.

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023 Background. A huge number of mathematical models are called Boussinesq equations; therefore, a wide range of sixth-order Boussinesq equations attracts a lot of attention from outside researchers around the world. Materials and methods.

Computing quantities of interest for random domains with second order shape sensitivity analysis [PDF]
, 2014 We consider random perturbations of a given domain. The characteristic amplitude of these perturbations is assumed to be small. We are interested in quantities of interest which depend on the random domain through a boundary value problem.

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 ...
