Geodesics in the compactly supported Hamiltonian diffeomorphism group
In this paper, geodesics in the group \({\mathcal D}\) of compactly supported Hamiltonian diffeomorphisms under Hofer's metric \(d\) are studied. We construct a family of geodesics with constant speeds in \(({\mathcal D},d)\) generated by time-dependent Hamiltonian functions.
