Some relation between spectral dimension and Ahlfors regular conformal dimension on infinite graphs

Probability 2026-04-06 v2

Abstract

The spectral dimension dsd_s of a weighted graph is an exponent associated with the asymptotic behavior of the random walk on the graph. The Ahlfors regular conformal dimension dimARC\dim_\mathrm{ARC} of the graph distance is a quasisymmetric invariant, where quasisymmetry is a well-studied property of homeomorphisms between metric spaces. In this paper, we give a typical example of a fractal-like graph with ds<dimARC<2d_s<\dim_\mathrm{ARC}<2 and prove a sufficient condition for dimARCds<2.\dim_\mathrm{ARC}\le d_s<2.
