Extra-large metrics

Igor Rivin

An extra large metric is a spherical cone metric with all cone angles greater than 2 pi and every closed geodesic longer than 2pi. We show that every two-dimensional extra large me…

Densities in free groups and $Z^{k}$ , Visible Points and Test Elements

Ilya Kapovich, Igor Rivin, Paul Schupp +1

In this article we relate two different densities. Let $F_{k}$ be the free group of finite rank $k \geq 2$ and let $α$ be the abelianization map from $F_{k}$ onto $Z^{k}$ . We pr…

Continuity of volumes -- on a generalization of a conjecture of J. W. Milnor

Igor Rivin

In his paper "On the Schlafli differential equality", J. Milnor conjectured that the volume of n-dimensional hyperbolic and spherical simplices, as a function of the dihedral angle…
