Let Ω be a bounded domain of with smooth boundary, , and let be a self-adjoint operator defined on a dense subspace such that A has an orthonormal basis of eigenfunctions in . For Y >0, giving the function , we consider the problem of finding a function such that In the system, the function is unknown and approximated by a given function such that for a small. This Cauchy problem is ill-posed and has many applications in physics and other fields. For this reason, a regularization for the problem is in order.
