The Plateau-Douglas problem for singular configurations and in general metric spaces

Paul Creutz, Martin Fitzi

Assume you are given a finite configuration of disjoint rectifiable Jordan curves in . The Plateau-Douglas problem asks whether there exists a minimizer of area a…

Rigidity of the Pu inequality and quadratic isoperimetric constants of normed spaces

Paul Creutz

Our main result gives an improved bound on the filling areas of closed curves in Banach spaces which are not closed geodesics. As applications we show rigidity of Pu's classical sy…

Maximal metric surfaces and the Sobolev-to-Lipschitz property

Paul Creutz, Elefterios Soultanis

We find maximal representatives within equivalence classes of metric spheres. For Ahlfors regular spheres these are uniquely characterized by satisfying the seemingly unrelated not…

Space of minimal discs and its compactification

Paul Creutz

We investigate the class of geodesic metric discs satisfying a uniform quadratic isoperimetric inequality and uniform bounds on the length of the boundary circle. We show that the…

Plateau's problem for singular curves

Paul Creutz

We give a solution of Plateau's problem for singular curves possibly having self-intersections. The proof is based on the solution of Plateau's problem for Jordan curves in very ge…

Majorization by Hemispheres & Quadratic Isoperimetric Constants

Paul Creutz

Let be a Banach space or more generally a complete metric space admitting a conical geodesic bicombing. We prove that every closed -Lipschitz curve may…
