The heaviness–SH-visibility conjecture

About 3 years old · traced to

Let (M,\a9ω)(M,\a9\omega) be a closed symplectic manifold and let K⊂MK\subset M be a compact subset. The subset KK is SH-visible when its relative symplectic cohomology satisfies

SHM(K;Λ)≠0,SH_M(K;\Lambda)\neq 0,

where Λ\Lambda is the Novikov field. Heaviness–SH-visibility conjecture. The subset KK is heavy if and only if it is SH-visible. This conjecture is motivated by the role of relative symplectic cohomology in detecting stable non-displaceability; the source states that it is confirmed in the paper.
