报告摘要:We consider the inverse problem of determining different type of  information about a diffusion process, described by fractional diffusion  equations stated on a bounded domain, like the density of the medium or the  velocity field associated with the moving quantities from a single boundary  measurement. This properties will be associated with some general class of time  independent coefficients that we recover from a single Neumann boundary  measurement, on some parts of the boundary, of the solution of our diffusion  equation with a suitable boundary input, located on some parts of the  boundary.
