T1 The Sobolev-type moment problem

AB We propose necessary and sufficient conditions for a bisequence of complex numbers to be a moment one of Sobolev type over the real line, the unit circle and the complex plane. We achieve this through converting the moment problem in question into a matrix one and utilizing some techniques coming from operator theory. This allows us to consider the Sobolev typemoment problem in its full generality, not necessarily in the diagonal case andeven of infinite order.
