Escrig D.F. (1986) Some probabilistic powerdomains in the category SFP. In: Monien B., Vidal-Naquet G. (eds) STACS 86. STACS 1986. Lecture Notes in Computer Science, vol 210. Springer, Berlin, Heidelberg
We define and study some definitions of probabilistic powerdomains over domains in SFP. We give three definitions: the first one is based in the notion of probability distribution over a domain; the second in probabilistic generating trees, that generalize the notion of generating tree, introduced by Smyth; and the last in "informations about probability distributions", that we introduce, getting an information system, as defined by Scott.
