Erratum: Lipschitz connectivity and filling invariants in solvable groups and buildings
Robert Young
This note corrects some omissions in section 2 of the paper "Lipschitz connectivity and filling invariants in solvable groups and buildings."
Lipschitz connectivity and filling invariants in solvable groups and buildings
Robert Young
We give some new methods, based on Lipschitz extension theorems, for bounding filling invariants of subsets of nonpositively curved spaces. We apply our methods to find sharp bound…
Lipschitz homotopy groups of the Heisenberg groups
Stefan Wenger, Robert Young
Lipschitz and horizontal maps from an -dimensional space into the -dimensional Heisenberg group $\H^n$ are abundant, while maps from higher-dimensional spaces are much m…
Pants decompositions of random surfaces
Larry Guth, Hugo Parlier, Robert Young
Our goal is to show, in two different contexts, that "random" surfaces have large pants decompositions. First we show that there are hyperbolic surfaces of genus for which any…
