Packing stability for symplectic $4$-manifolds
Packing stability for symplectic $4$-manifolds
The packing stability in symplectic geometry was first noticed by Biran (1997): the symplectic obstructions to embed several balls into a manifold disappear when their size is small enough. This phenomenon is known to hold for all closed manifolds with rational symplectic class, as well as for all ellipsoids. In …
