Remark on non-contractible closed geodesics and homotopy groups
Egor Shelukhin, Jun Zhang
We prove that if the -th homotopy group for of a closed manifold has non-trivial invariants or coinvariants under the action of the fundamental group, then there exis…
Enlacements asymptotiques revisités
Egor Shelukhin
We give an alternative proof of a theorem of Gambaudo-Ghys and Fathi on the interpretation of the Calabi homomorphism for the standard symplectic disc as an average rotation number…
Proof of the main conjecture on g-areas
François Lalonde, Egor Shelukhin
In this paper, we prove the main conjecture on -areas that was announced by the first author in 2004. It states that the -area of any Hamiltonian diffeomorphism is equal…
On the -geometry of autonomous Hamiltonian diffeomorphisms of surfaces
Michael Brandenbursky, Egor Shelukhin
We prove a number of results on the interrelation between the -metric on the group of Hamiltonian diffeomorphisms of surfaces and the subset of all autonomous Hamiltonian diff…
