The problem of recovering functions given incomplete information contained in the sequence of their moments or the values of Laplace transforms represents special case of the so-called ill-posed problem. Several approximations and corresponding upper bounds for the uniform and L1-rates of convergences are derived. Applications in computed tomography and statistics including the problem of recovering the derivatives, and the support of function will be outlined. In particular, reconstruction of a function from the values of its Radon transform (projections) will be discussed as well.
