Survey on invariant quasimorphisms and stable mixed commutator length

Morimichi Kawasaki, Mitsuaki Kimura, Shuhei Maruyama +2

A homogeneous quasimorphism $ϕ$ on a normal subgroup $N$ of $G$ is said to be $G$ -invariant if $ϕ (g x g^{- 1}) = ϕ (x)$ for every $g \in G$ and for every $x \in N$ . Invariant quasimorp…

Mixed commutator lengths, wreath products and general ranks

Morimichi Kawasaki, Mitsuaki Kimura, Shuhei Maruyama +2

In the present paper, for a pair $(G, N)$ of a group $G$ and its normal subgroup $N$ , we consider the mixed commutator length $cl_{G, N}$ on the mixed commutator subgroup $[…
