• Square positive functionals
• representing measures
• idempotents
• characters
• polynomial interpolation

We present a new approach to truncated and full moment problems, via idempotent elements with respect to associated square positive Riesz functionals. The existence of representing measures for such functionals is characterized via some intrinsic conditions.
