Some closed manifolds that do not fibre over the circle

Sam Hughes, Ian Leary, Wolfgang Lueck

We construct closed manifolds with vanishing L^2-Betti numbers over every field) which do not virtually fibre over the circle. The class of fundamental groups that occurs is the la…

Higher topological complexity of hyperbolic groups

Sam Hughes, Kevin Li

We prove for non-elementary torsion-free hyperbolic groups $Γ$ and all $r \geq 2$ that the higher topological complexity $TC_{r} (Γ)$ is equal to $r \cdot cd (Γ)$ . In part…
