Invariant Parabolic equations and Markov process on Adéles
V. A. Aguilar-Arteaga, S. Estala-Arias
In this article a class of additive invariant positive selfadjoint pseudodifferential unbounded operators on , where is the ring of finite a…
Harmonic Analysis on the Adèle Ring of $\Q$
Victor A. Aguilar-Arteaga, Manuel Cruz-López, Samuel Estala-Arias
The ring of finite adèles $\Af$ of the rational numbers $\Q$ is obtained in this article as a completion of $\Q$ with respect to a certain non--Archimedean metric. This ultrametric…
A Heat Equation on some Adic Completions of Q and Ultrametric Analysis
Victor A. Aguilar-Arteaga, Manuel Cruz-López, Samuel Estala Arias
This article deals with a Markov process related to the fundamental solution of a heat equation on the direct product ring Q_S, where Q_S is a finite direct product of p-adic field…
