Infinite convolutions of probability measures on Polish semigroups
Infinite convolutions of probability measures on Polish semigroups
This expository paper is intended for a short self-contained introduction to the theory of infinite convolutions of probability measures on Polish semigroups. We give the proofs of the Rees decomposition theorem of completely simple semigroups, the EllisāÅ»elazko theorem, the convolution factorization theorem of convolution idempotents, and the convolution factorization theorem ā¦
