Calabi quasi-morphisms for some non-monotone symplectic manifolds
Calabi quasi-morphisms for some non-monotone symplectic manifolds
In this work we construct Calabi quasi-morphisms on the universal cover of the group Ham(M) of Hamiltonian diffeomorphisms for some non-monotone symplectic manifolds. This complements a result by Entov and Polterovich which applies in the monotone case. Moreover, in contrast to their work, we show that these quasi-morphisms descend to …
