Upper bound for the Gromov width of flag manifolds
Alexander Caviedes Castro · Journal of Symplectic Geometry · 2015
We find an upper bound for the Gromov width of coadjoint orbits of U (n) with respect to the Kirillov-Kostant-Souriau symplectic form by computing certain Gromov-Witten invariants.The approach presented here is closely related to the one used by Gromov in his celebrated non-squeezing theorem.
