On conjugation invariant norms, asymptotic cones, metric ultraproducts and contractibility
Bastien Karlhofer
In the present paper we prove lemmata on strong contractibility in asymptotic cones and metric ultraproducts which we apply to both the case of finitely generated word norms and th…
Aut-invariant quasimorphisms on graph products of abelian groups
Bastien Karlhofer
The present paper constructs unbounded quasimorphisms that are invariant under all automorphisms on free products of more than two factors and on graph products of finitely generat…
Aut-invariant quasimorphisms on free products
Bastien Karlhofer
Let be a free product of freely indecomposable groups. We explicitly construct quasimorphisms on which are invariant with respect to all automorphisms of . We a…
Qualitative counting closed geodesics
Bastien Karlhofer, Jarek Kędra, Michał Marcinkowski +1
We investigate the geometry of word metrics on fundamental groups of manifolds associated with the generating sets consisting of elements represented by closed geodesics. We ask wh…
