摘要

In this article, we introduce a class of Lévy processes on certain totally disconnected groups. These processes are described by their Markov transition functions, as in the classical p-adic theory of the Vladimirov operator, and its corresponding Lévy process. An outstanding application of this work is accomplished on the ring of finite adèles, a locally compact topological ring which supports several Vladimirov-type pseudodifferential operators, corresponding to different Lévy processes on it.
