A compositional framework for open classical kinematic systems

Andrea Abeje-Stine, David Weisbart

Our aim is to introduce a framework sufficiently general to describe the kinematics of a wide variety of open systems in classical mechanics while uniquely characterizing systems w…

Geometry-induced criticality in -adic scaling limits of random walks

Rahul Rajkumar, David Weisbart

An anisotropy parameter in induces on a duality-compatible, two-scale filtration that collapses to one scale at the right endpoint. This filtration def…

Brownian Motion in the -Adic Integers is a Limit of Discrete Time Random Walks

Tyler Pierce, David Weisbart

Vladimirov defined an operator on balls in , the -adic numbers, that is analogous to the Laplace operator in the real setting. Kochubei later provided a probabilist…

Brownian Motion in a Vector Space over a Local Field is a Scaling Limit

Tyler Pierce, Rahul Rajkumar, Andrea Stine +2

For any natural number , the Vladimirov-Taibleson operator is a natural analogue of the Laplace operator for complex-valued functions on a -dimensional vector space over…

Components and Exit Times of Brownian Motion in two or more -Adic Dimensions

Rahul Rajkumar, David Weisbart

The fundamental solution of a pseudo-differential equation for functions defined on the -fold product of the -adic numbers, , induces an analogue of the Wiener…

-Adic Brownian Motion is a Scaling Limit

David Weisbart

A -adic Brownian motion is a continuous time stochastic process in a -adic state space that has a Vladimirov operator as its infinitesimal generator. The current work shows t…
