Locally elliptic actions, torsion groups, and nonpositively curved spaces

Thomas Haettel, Damian Osajda

Extending and unifying a number of well-known conjectures and open questions, we conjecture that locally elliptic (that is, every element has a bounded orbit) actions by automorphi…

Lattices, injective metrics and the $K (π, 1)$ conjecture

Thomas Haettel

Starting with a lattice with an action of $Z$ or $R$ , we build a Helly graph or an injective metric space. We deduce that the $ℓ^{\infty}$ orthoscheme complex of…
