%0 Book Section %T Some probabilistic powerdomains in the category SFP publisher Springer %D 1986 %U 978-3-540-16078-6 %@ https://hdl.handle.net/20.500.14352/65445 %X 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. %~
