The symmetries of outer space

open access: yesDuke Mathematical Journal, 2001
The authors investigate the natural map \(\text{Out}(F_n)\to\Aut(K_n)\) from the outer automorphism group of the free group of rank \(n\), \(F_n\), to the group of the spine, \(K_n\), of outer space and prove that for \(n\geq 3\), this natural map is an isomorphism.

A chronopolitics of outer space : a poetics of tomorrowing

open access: yes, 2023
This chapter centres on the expediency of ‘futurity’ as an epistemic angle to describe how diverse narrative framings articulate differently the horizons of anticipation, hope, and speculation of space futures.
