Bi-invariant metrics and quasi-morphisms on groups of Hamiltonian diffeomorphisms of surfaces
M Brandenbursky - International Journal of Mathematics, 2015 - World Scientific
Let Σg be a closed orientable surface of genus g and let Diff 0 (Σg, area) be the identity
component of the group of area-preserving diffeomorphisms of Σg. In this paper, we present …
