Approximation, regularity and positivity preservation on Riemannian manifolds

S Pigola, D Valtorta, G Veronelli - Nonlinear Analysis, 2024 - Elsevier
The paper focuses on the L p-Positivity Preservation property (L p-PP for short) on a
Riemannian manifold (M, g). It states that any L p function u with 1< p<+∞, which solves …

Stochastic completeness of graphs: bounded Laplacians, intrinsic metrics, volume growth and curvature

RK Wojciechowski - Journal of Fourier Analysis and Applications, 2021 - Springer
The goal of this article is to survey various results concerning stochastic completeness of
graphs. In particular, we present a variety of formulations of stochastic completeness and …

Essential self-adjointness of the Laplacian on weighted graphs: harmonic functions, stability, characterizations and capacity

A Inoue, S Ku, J Masamune… - arxiv preprint arxiv …, 2024 - arxiv.org
We give two characterizations for the essential self-adjointness of the weighted Laplacian on
birth-death chains. The first involves the edge weights and vertex measure and is classically …

Self‐adjointness of non‐semibounded covariant Schrödinger operators on Riemannian manifolds

O Milatovic - Mathematische Nachrichten, 2023 - Wiley Online Library
In the context of a geodesically complete Riemannian manifold M, we study the self‐
adjointness of∇†∇+ V ∇^\dagger∇+V, where∇ is a metric covariant derivative (with formal …
