Continuity conjecture for relative symplectic cohomology

Less than 1 year old · traced to

Let (M,bomega)(M,bomega) be a closed symplectic manifold and let K0⊂MK_0\subset M be a compact subset. The relative symplectic cohomology SHM(K;Λ≥0)SH_M(K;\Lambda_{\geq0}) is defined for compact subsets K⊂MK\subset M, with restriction maps inducing a directed system over compact KK satisfying K0⊂Int⁡(K)K_0\subset\operatorname{Int}(K). Continuity conjecture.

lim→⁡K0⊂Int⁡(K)K is compactSHM(K;Λ≥0)=SHM(K0;Λ≥0).\underset{\substack{K_0\subset \operatorname{Int}(K) \\ K\text{ is compact}}}{\varinjlim} SH_M(K;\Lambda_{\geq0})=SH_M(K_0;\Lambda_{\geq0}).

The paper establishes this identity in the special case of standard toric balls in complex projective space, while the general continuity property for relative symplectic cohomology remains the proposed extension.
