Weak Laplacian bounds and minimal boundaries in non-smooth spaces with Ricci curvature lower bounds

A Mondino, D Semola - arXiv preprint arXiv:2107.12344, 2021 - arxiv.org
The goal of the paper is four-fold. In the setting of non-smooth spaces with Ricci curvature
lower bounds (more precisely RCD (K, N) metric measure spaces):-we develop an intrinsic …

Asymptotically mean value harmonic functions in subriemannian and RCD settings

T Adamowicz, A Kijowski, E Soultanis - The Journal of Geometric Analysis, 2023 - Springer
We consider weakly and strongly asymptotically mean value harmonic (amv-harmonic)
functions on subriemannian and RCD settings. We demonstrate that, in non-collapsed RCD …

Asymptotic mean value Laplacian in metric measure spaces

A Minne, D Tewodrose - Journal of Mathematical Analysis and Applications, 2020 - Elsevier
We use the mean value property in an asymptotic way to provide a notion of a pointwise
Laplacian, called AMV Laplacian, that we study in several contexts including the Heisenberg …
