Acceptance of an infinite input word requires that the probability for the accepting runs is positive. In this paper, we provide a summary of the fundamental properties of probabilistic omega-automata concerning expressiveness, efficiency, compositionality and decision problems %U http://www.irisa.fr/vertecs/Publis/Ps/2009-sofsem.pdf %U http://dx.doi.org/10.1007/978-3-540-95891-8_3 %D 2009
