A solution of Gromov's Hölder equivalence problem for the Heisenberg group
Roger Züst
We show that a map with Hölder exponent bigger than from a quasi-convex metric space with vanishing first Lipschitz homology into the Sub-Riemannian Heisenberg group factors…

Matchings in metric spaces, the dual problem and calibrations modulo 2
Mircea Petrache, Roger Züst
We show that for a metric space with an even number of points there is a 1-Lipschitz map to a tree-like space with the same matching number. This result gives the first basic versi…

Some properties of Hölder surfaces in the Heisenberg group
Enrico Le Donne, Roger Züst
It is a folk conjecture that for alpha > 1/2 there is no alpha-Hoelder surface in the subRiemannian Heisenberg group. Namely, it is expected that there is no embedding from an open…
