Equivariant discretizations of diffusions, random walks, and harmonic functions: Corrections and additions
Year: 2025
Type: article
Abstract: The Martin boundary of a diffusion process on a manifold consists of positive harmonic functions. In a previous publication, we erroneously assumed that the same holds for discretizations of diffusions. In this article, we correct this mistake and extend some of our previous results.
