VII: 22, 217-222, LNM 321 (1973) MEYER, Paul-André Sur les désintégrations régulières de L. Schwartz (General theory of processes) This paper presents a small part of an important article of L.~Schwartz (J. Anal. Math., 26, 1973). The main result is an extension of the classical theorem on the existence of regular conditional probability distributions: on a good filtered probability space, the previsible and optional projections of a process can be computed by means of true kernels Comment: The contents of this paper have been considerably developed by F.~Knight in his theory of prediction.
