Entropy and quasimorphisms

Michael Brandenbursky, Michał Marcinkowski

Let $S$ be a compact oriented surface. We construct homogeneous quasimorphisms on $D i f f (S, a r e a)$ , on $D i f f_{0} (S, a r e a)$ and on $H am (S)$ generalizing the constructions of Gambaudo-G…

Aut-invariant norms and Aut-invariant quasimorphisms on free and surface groups

Michael Brandenbursky, Michał Marcinkowski

Let $F_{n}$ be the free group on $n$ generators and $Γ_{g}$ the surface group of genus $g$ . We consider two particular generating sets: the set of all primitive elements in $F_{n}$ and t…
