In this article, we study inverse source problems for time-fractional diffusion equations from a posteriori boundary measurement. Using the memory effect of these class equations, solve several space- or time-dependent terms. We prove also unique determination general space–time-dependent separated variables terms such Our approach is based on singularities Laplace transform in time traces solu...

We consider an inverse boundary value problem for a nonlinear elastic wave equation which was studied in [1] . show that all the parameters appearing can be uniquely determined from measurements under certain geometric assumptions. The proof is based on second order linearization and Gaussian beams. Nous considérons un problème avec données au bord, pour une équation des ondes élastiques non-li...
