Higher topological complexity of hyperbolic groups

Algebraic Topology 2025-01-15 v1 Group Theory

Abstract

We prove for non-elementary torsion-free hyperbolic groups Γ\Gamma and all r2r\ge 2 that the higher topological complexity TCr(Γ){\sf{TC}}_r(\Gamma) is equal to rcd(Γ)r\cdot \mathrm{cd}(\Gamma). In particular, hyperbolic groups satisfy the rationality conjecture on the TC\sf{TC}-generating function, giving an affirmative answer to a question of Farber and Oprea. More generally, we consider certain toral relatively hyperbolic groups.
