We consider the inverse problem of determining the Lamé parameters and the density of a three-dimensional elastic body from the local time-harmonic Dirichlet-to-Neumann map. We …
We propose a novel numerical inversion algorithm for the coefficients of parabolic partial differential equations, based on model reduction. The study is motivated by the application …
We consider the inverse boundary value problem of determining the potential q in the equation Δ u+ qu= 0 in Ω⊂ R n, from local Cauchy data. A result of global Lipschitz stability …
We study an inverse boundary value problem for the Helmholtz equation using the Dirichlet- to-Neumann map. We consider piecewise constant wave speeds on an unknown tetrahedral …

We study the inverse problem in Optical Tomography of determining the optical properties of a medium $\Omega\subset\mathbb {R}^ n $, with $ n\geq 3$, under the so-called diffusion …
We study the solution of the system of equations describing the dynamical evolution of spontaneous ruptures generated in a prestressed elastic-gravitational deforming body and …

We consider the seismic inverse problem in the case of the time-harmonic elastic isotropic wave equation, in particular for the recovery of the Lamé parameters. We employ full …
In seismology, people use waves generated by earthquakes, artificial explosions, or even" noises", to detect the Earth's interior structure. The waves traveling in rocks, which are the …
We present a novel method to simulate the propagation of seismic waves in realistic fluid- solid materials, coupled with dynamically evolving faults, in the self-gravitating prestressed …
