Quasimorphisms (QM) of groups to the reals are well studied and are linked to stable commutator length (scl) via Bavard Duality- Theorem. The notion of QM can be generalized to yield maps between groups such that each QM from one group pulls back to a QM in the other.
We will give both a short overview of features of scl and investigate these generalized QMs with large scale properties of the commutator group.
