Filling functions of arithmetic groups

Enrico Leuzinger, Robert Young

The Dehn function and its higher-dimensional generalizations measure the difficulty of filling a sphere in a space by a ball. In nonpositively curved spaces, one can construct fill…

The distortion dimension of $Q$ --rank $1$ lattices

Enrico Leuzinger, Robert Young

Let $X = G / K$ be a symmetric space of noncompact type and rank $k \geq 2$ . We prove that horospheres in $X$ are Lipschitz $(k - 2)$ --connected if their centers are not contained in a pro…
