The Gromov width of a symplectic manifold is the supremum of the capacities of standard open symplectic balls that embed smoothly
into it while preserving the symplectic form.
In standard coordinates 
, the ball
of capacity 
is
 |
Its Euclidean radius is 
, and its volume is 
. For an open subset 
of standard symplectic space,
its width is
 |
