| Feb 8, 2013 at 17:08 | comment | added | alvarezpaiva | Is there any intuition/general principle around the non-vanishing of the geodesic distance for a weak metric? In symplectic geometry basically only the $L_\infty$ bi-invariant Finsler metric in the Hamiltonian symplectomorphism group has non-vanishing distance. Is it always that rare to have non-vanishing distance? | |
