We are concerned with the reconstruction of the heat capacity coefficient of a one-dimensional heat equation from a sequence of observations of solutions at a single fixed point. This new direct me...

We are concerned with the inverse problem of recovering the unknown wave speed and also the source in a multidimensional wave equation. We show that the wave speed coefficient can be reconstructed from the observations of the solution taken at a sing

We are concerned with the inverse problem of recovering a third order Moore-Gibson-Thompson equation from a single observation of its solution at an arbitrary point. We show how to reconstruct its three unknown parameters and the memory kernel by usi

We are concerned with the inverse spectral problem for a quadratic pencil operator. We show that one given spectrum is enough for its reconstruction in the case of one analytic potential. To do so ...

We use the sampling method to compute the eigenvalues of a quadratic pencil. To do so we first prove a non standard representation of the eigensolution that allows us to decompose the characteristic function into Paley-Wiener functions. Numerical exa

We show how to reconstruct the shape of a solid of revolution by measuring its temperature on the boundary. This inverse problem reduces to finding a coefficient of a parabolic equation from values of the trace of its solution on the boundary. This i

We approach the subject of transmutations from the operator theoretic point of view and use them to compare general differential operators, and Krein’s type of strings. We also examine their existence, construction, and their various applications t
