The category of probabilistic coherence spaces (PCoh_!), introduced by Danos and Ehrhard, is a fully abstract model for PCF with *discrete* probabilities, where morphisms can be seen as power series. The category Cstab_m, of measurable cones and measurable stable functions, has been introduced by Ehrhard, Pagani and Tasson as a model for PCF with *continuous* probabilities. In this talk, we will study the shape of stable functions when they are between *discrete* cones, and it will allow us to see that PCoh_! is a full subcategory of Cstab_m.
