Abstract:
We introduce a probabilistic version of Plotkin’s PCF, a paradigmatic functional programming language. We also describe a denotational model for this language, based on probabilistic coherence spaces, and we prove adequacy and full abstraction for this interpretation, introducing an innovative method. This is a joint work with C. Tasson and M. Pagani, published in POPL’14.
