    Packing stability for symplectic 4-manifolds.
    (AMS, 2016-11) Buse, Olguta; Hind, Richard; Opshtein, Emmanuel; Department of Mathematical Sciences, School of Science
    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 this note, we show that packing stability holds for all closed, and several open, symplectic $ 4$-manifolds.
