Monotonicity formulas for harmonic functions on the infinite regular tree

Analysis of PDEs 2026-03-16 v1

Abstract

We continue the program initiated in \cite{SVGS}. In this paper, we focus on the infinite dd-regular tree, and prove the monotonicity of a weighted Dirichlet energy, a Weiss-type monotonicity formula, and a generalization of the Almgren monotonicity formula of \cite{SVGS} for p1p\ge 1. We also compute examples in the infinite 22- and 33-regular trees.
