Symplectic embeddings of 4-dimensional ellipsoids into polydiscs
Abstract
McDuff and Schlenk have recently determined exactly when a four-dimensional symplectic ellipsoid symplectically embeds into a symplectic ball. Similarly, Frenkel and M\"uller have recently determined exactly when a symplectic ellipsoid symplectically embeds into a symplectic cube. Symplectic embeddings of more complicated structures, however, remain mostly unexplored. We study when a symplectic ellipsoid symplectically embeds into a polydisc . We prove that there exists a constant depending only on (here, is assumed greater than ) such that if is greater than , then the only obstruction to symplectically embedding into is the volume obstruction. We also conjecture exactly when an ellipsoid embeds into a scaling of for greater than or equal to , and conjecture about the set of such that the only obstruction to embedding into a scaling of is the classical volume. Finally, we verify our conjecture for .
