Instead, one is concerned with mere probabilities. Consequently, it is a very important task to determine the basic probabilities associated with a given system. In this snapshot we will present a recent uniqueness result concerning these probabilities.enghttps://creativecommons.org/licenses/by-nc-sa/3.0/510AnalysisProbability Theory and StatisticsThe Kadison-Singer problemReport5 S.
