International audienceLet X be a metric space and B its Borel cr-algebra. Let AI the space of bounded signed measures on B. In order to construct the signed random measures as hilbertian random variables we use the embedding of AI in a separable reproducing kernel space Hk. That construction is effectively possible when X is compact or locally compact or separable. Mesurability problems due to embedding are resolved in these three cases. Real random variables naturally associated with a so defined random measure //* are ingrains of Hr elements with respect to /i*. For random sequences and their associated random variables, three modes of convergence are studied (almost surely, in probability, in law)Soit B la tribu borélienne d’un espace mé...
