Lipschitz extensions into Jet space Carnot groups
Stefan Wenger, Robert Young
The aim of this article is to prove a Lipschitz extension theorem for partially defined Lipschitz maps to jet spaces endowed with a left-invariant sub-Riemannian Carnot-Carathéodor…

A polynomial isoperimetric inequality for SL(n,Z)
Robert Young
We prove that when n>=5, the Dehn function of SL(n,Z) is at most quartic. The proof involves decomposing a disc in SL(n,R)/SO(n) into a quadratic number of loops in generalized Sie…

Homological and homotopical higher-order filling functions
Robert Young
We construct groups in which FV^3(n) != δ^2(n). This construction also leads to groups G_k, k >= 3 for which δ^{k}(n) is not subrecursive.
