Symplectophagy — Draconitic Research

Abstract

We introduce the notion of a symplectophagy, which is a symplectic isotopy satisfying conditions reminiscent of the symplectic camel. We present new symplectic rigidity results which take the form of obstructions to the existence of symplectophagies in certain situations. The main tool is the relative symplectic cohomology recently introduced by Varolgunes, as well as its extension to pairs, due to the authors and L. Polterovich, for which we establish an invariance property, which is the chief technical novelty of the present paper. An important role is also played by the recent calculations of relative symplectic cohomology in complex projective spaces due to Dickstein-Ganor.
