Harmonic analysis of a source identification problem [PDF]
Quarterly of Applied Mathematics, 1982 This paper presents the problem of identifying a source in a porous medium which hosts a steady flow field. The medium properties and the velocity potential are assumed known. The known functions will be considered as deterministic at first. The stochastic source identification problem will be considered later.

The spacewise dependent source identification problem for the elliptic-telegraph differential equation with involution and Robin condition [PDF]
E-Journal of Analysis and Applied Mathematics, 2023 In the present paper, the spacewise dependent source identification problem (SIP) for the elliptic-telegraph differential equation with involution and Robin condition is investigated. The theorem on stability estimates for the solution of this space-wise

A new approach to nonlinear constrained Tikhonov regularization [PDF]
, 2011 We present a novel approach to nonlinear constrained Tikhonov regularization from the viewpoint of optimization theory. A second-order sufficient optimality condition is suggested as a nonlinearity condition to handle the nonlinearity of the forward ...

Point source identification in non-linear advection-diffusion-reaction systems
, 2013 We consider a problem of identification of point sources in time dependent advection-diffusion systems with a non-linear reaction term. The linear counterpart of the problem in question can be reduced to solving a system of non-linear algebraic equations
