Metric properties of Outer Space [PDF]

open access: yesPublicacions Matemàtiques, 2011
We define metrics on Culler-Vogtmann space, which are an analogue of the Teichmuller metric and are constructed using stretching factors. In fact the metrics we study are related, one being a symmetrised version of the other. We investigate the basic properties of these metrics, showing the advantages and pathologies of both choices.

PING-PONG AND OUTER SPACE [PDF]

open access: yesJournal of Topology and Analysis, 2010
We prove that, if φ, ψ ∈ Out (FN) are hyperbolic iwips (irreducible with irreducible powers) such that 〈φ, ψ〉 ⊆ Out (FN) is not virtually cyclic, then some high powers of φ and ψ generate a free subgroup of rank two for which all nontrivial elements are again hyperbolic iwips.

On the q-Laplace Transform and Related Special Functions

open access: yesAxioms, 2016
Motivated by statistical mechanics contexts, we study the properties of the q-Laplace transform, which is an extension of the well-known Laplace transform. In many circumstances, the kernel function to evaluate certain integral forms has been studied. In

RELATIVE TWISTING IN OUTER SPACE [PDF]

open access: yesJournal of Topology and Analysis, 2012
Subsurface projection is indispensable to studying the geometry of the mapping class group and the curve complex of a surface. When the subsurface is an annulus, this projection is sometimes called relative twisting. We give two alternate versions of relative twisting for the outer automorphism group of a free group.

War and peace in outer space ::law, policy, and ethics /

open access: yes, 2021
This work explores the legal and ethical issues surrounding the increased weaponization of outer space and the potential for space-based conflict. The essays included explore the moral and legal issues in four sections covering the legal framework ...

Stability in Outer space

open access: yesGroups, Geometry, and Dynamics, 2018
We characterize strongly Morse quasi-geodesics in Outer space as quasi-geodesics which project to quasi-geodesics in the free factor graph. We define convex cocompact subgroups of Out (F_n) as subgroups such that an orbit map in the free factor ...
