摘要

We associate two specific projective systems of probability spaces to any Tsirelson convolution system. If the corresponding projective limit (in the sense of Bochner) exists, we say that the system is convergent in the first case and K-convergent in the second. It is shown that convergent convolution systems give rise to continuous products of probability spaces, while K-convergent systems lead to flow systems. We then investigate the relationship between convergence and K-convergence, as well as their connections to two-parameter product systems of Hilbert spaces.
