Lipschitz extension theorems with explicit constants

Giuliano Basso

In this mostly expository article, we give streamlined proofs of several well-known Lipschitz extension theorems. We pay special attention to obtaining statements with explicit exp…

Geometric and analytic structures on metric spaces homeomorphic to a manifold

Giuliano Basso, Denis Marti, Stefan Wenger

We study metric spaces homeomorphic to a closed oriented manifold from both geometric and analytic perspectives. We show that such spaces (which are sometimes called metric manifol…

A non-compact convex hull in generalized non-positive curvature

Giuliano Basso, Yannick Krifka, Elefterios Soultanis

In this article, we are interested in metric spaces that satisfy a weak non-positive curvature condition in the sense that they admit a conical geodesic bicombing. We show that the…

Undistorted fillings in subsets of metric spaces

Giuliano Basso, Stefan Wenger, Robert Young

We prove that if a quasiconvex subset of a metric space has finite Nagata dimension and is Lipschitz -connected or admits Euclidean isoperimetric inequalities up to dime…

Absolute Lipschitz extendability and linear projection constants

Giuliano Basso

We prove that the absolute extendability constant of a finite metric space may be determined by computing relative projection constants of certain Lipschitz-free spaces. As an appl…

Approximating spaces of Nagata dimension zero by weighted trees

Giuliano Basso, Hubert Sidler

We prove that if a metric space has Nagata dimension zero with constant , then there exists a dense subset of that is -bilipschitz equivalent to a weighted tree. The…

Extending and improving conical bicombings

Giuliano Basso

We study metric spaces that admit a conical bicombing and thus obey a weak form of non-positive curvature. Prime examples of such spaces are injective metric spaces. In this articl…

Computation of maximal projection constants

Giuliano Basso

The linear projection constant of a finite-dimensional real Banach space is the smallest number such that is a -absolute retract in the categor…

Lipschitz extensions to finitely many points

Giuliano Basso

We consider Lipschitz maps with values in quasi-metric spaces and extend such maps to finitely many points. We prove that in this context every 1-Lipschitz map admits an extension…

Conical geodesic bicombings on subsets of normed vector spaces

Giuliano Basso, Benjamin Miesch

We prove existence and uniqueness results for conical geodesic bicombings on subsets of normed vector spaces. Concerning existence, we give a first example of a non-consistent conv…

Fixed point theorems for metric spaces with a conical geodesic bicombing

Giuliano Basso

We derive two fixed point theorems for a class of metric spaces that includes all Banach spaces and all complete Busemann spaces. We obtain our results by the use of a 1-Lipschitz…
