The Quasi-hyperbolicity Constant of a Metric Space
George Dragomir, Andrew Nicas
We introduce the quasi-hyperbolicity constant of a metric space, a rough isometry invariant that measures how a metric space deviates from being Gromov hyperbolic. This number, for…

Metric transforms yielding Gromov hyperbolic spaces
George Dragomir, Andrew Nicas
A real valued function of one variable is called a metric transform if for every metric space the composition is also a metric on . We give a complet…

The Stratification of Singular Locus and Closed Geodesics on Orbifolds
George Dragomir
In this note, we prove the existence of a closed geodesic of positive length on any compact developable orbifold of dimension 3, 5, or 7. The argument uses the stratification of th…
