  This paper provides an analysis of different formal representations of
beliefs in epistemic game theory. The aim is to attempt a synthesis of
different structures of beliefs in the presence of indeterminate probabilities.
Special attention is also paid to the decision-theoretic principle known as the
thesis of no subjective probability for self-action. Conditions in cope with
this principle are given which underlie the interrelationships between
different models of beliefs, and it is shown that under these conditions
different doxastic structures can be coherently unified.
