Area minimizing discs in metric spaces

A Lytchak, S Wenger - Archive for Rational Mechanics and Analysis, 2017 - Springer
We solve the classical problem of Plateau in the setting of proper metric spaces. Precisely,
we prove that among all disc-type surfaces with prescribed Jordan boundary in a proper …

Polyhedral approximation of metric surfaces and applications to uniformization

D Ntalampekos, M Romney - Duke Mathematical Journal, 2023 - projecteuclid.org
We prove that any length metric space homeomorphic to a 2-manifold with boundary, also
called a length surface, is the Gromov–Hausdorff limit of polyhedral surfaces with controlled …

Polyhedral approximation and uniformization for non-length surfaces

D Ntalampekos, M Romney - Journal of the European Mathematical …, 2024 - ems.press
We prove that any metric surface (that is, metric space homeomorphic to a 2-manifold with
boundary) with locally finite Hausdorff 2-measure is the Gromov–Hausdorff limit of …

Canonical parameterizations of metric disks

A Lytchak, S Wenger - 2020 - projecteuclid.org
We use the recently established existence and regularity of area and energy minimizing
disks in metric spaces to obtain canonical parameterizations of metric surfaces. Our …

Intrinsic structure of minimal discs in metric spaces

A Lytchak, S Wenger - Geometry & Topology, 2017 - msp.org
We study the intrinsic structure of parametric minimal discs in metric spaces admitting a
quadratic isoperimetric inequality. We associate to each minimal disc a compact, geodesic …

Quasiconformal almost parametrizations of metric surfaces

D Meier, S Wenger - Journal of the European Mathematical Society, 2024 - ems.press
We look for minimal conditions on a two-dimensional metric surface X of locally finite
Hausdorff 2-measure under which X admits an (almost) parametrization with good geometric …

Maximal metric surfaces and the Sobolev-to-Lipschitz property

P Creutz, E Soultanis - Calculus of Variations and Partial Differential …, 2020 - Springer
We find maximal representatives within equivalence classes of metric spheres. For Ahlfors
regular spheres these are uniquely characterized by satisfying the seemingly unrelated …

Area minimizing surfaces of bounded genus in metric spaces

M Fitzi, S Wenger - Journal für die reine und angewandte Mathematik …, 2021 - degruyter.com
Abstract The Plateau–Douglas problem asks to find an area minimizing surface of fixed or
bounded genus spanning a given finite collection of Jordan curves in Euclidean space. In …

Quasiconformal uniformization of metric surfaces of higher topology

D Meier - arXiv preprint arXiv:2208.11564, 2022 - arxiv.org
We establish the following uniformization result for metric spaces $ X $ of finite Hausdorff 2-
measure. If $ X $ is homeomorphic to a smooth 2-manifold $ M $ with non-empty boundary …

Majorization by hemispheres and quadratic isoperimetric constants

P Creutz - Transactions of the American Mathematical Society, 2020 - ams.org
Let $ X $ be a Banach space or more generally a complete metric space admitting a conical
geodesic bicombing. We prove that every closed $ L $-Lipschitz curve $\gamma: S …
