Resume: We deal with randomvariables and their distributions, 1-dimensional or multidimensional, discreteor continuous, assuming they have finite all integer positive order moments.Any such a distribution is either uniquely determined by its moments, and wesay that it is M-determinate, or it is non-unique, M-indeterminate.
There are classicalconditions, including of the type “iff”, however they are all uncheckable. In this talk the main discussionwill be on conditions which are either only sufficient or only necessary, butthey all can be relatively easily checked. There are some very recent results,some of them will be presented. Illustrations will be given, and if timepermits, a few open questions will be formulated.
