[HTML][HTML] Characterizing Sobolev spaces of vector-valued functions

I Caamaño, JÁ Jaramillo, Á Prieto - Journal of Mathematical Analysis and …, 2022 - Elsevier
We are concerned here with Sobolev-type spaces of vector-valued functions. For an open
subset Ω⊂ RN and a Banach space V, we characterize the functions in the Sobolev …

An approach to metric space-valued Sobolev maps via weak* derivatives

P Creutz, N Evseev - Analysis and Geometry in Metric Spaces, 2024 - degruyter.com
We give a characterization of metric space-valued Sobolev maps in terms of weak*
derivatives. More precisely, we show that Sobolev maps with values in dual-to-separable …

Monge-Kantorovich Fitting With Sobolev Budgets

F Kobayashi, J Hayase, YH Kim - arxiv preprint arxiv:2409.16541, 2024 - arxiv.org
We consider the problem of finding the``best''approximation of an $ n $-dimensional
probability measure $\rho $ using a measure $\nu $ whose support is parametrized by …

Vector-valued Sobolev spaces based on Banach function spaces

N Evseev - Nonlinear Analysis, 2021 - Elsevier
It is known that there are several approaches to define a Sobolev class for Banach valued
functions. We compare the usual definition via weak derivatives with the Reshetnyak …

Bochner Partial Derivatives, Cheeger-Kleiner Differentiability, and Non-Embedding

K Wildrick - arxiv preprint arxiv:2307.10857, 2023 - arxiv.org
Among all Poincar\'e inequality spaces, we define the class of Cheeger fractals, which
includes the sub-Riemannian Heisenberg group. We show that there is no bi-Lipschitz …
