Abstract
Extension results, expressed in terms of complete boundedness, leading to necessary and sufficient conditions
for the solvability of power moment problems with unbounded operator data are given. As an
application, necessary and sufficient conditions for the existence of selfadjoint and normal extensions for
some classes of commuting tuples of unbounded linear operators are obtained.
