Holomorphic Seifert–Weinstein conjecture for locally conformally symplectic manifolds

Let S2k+1×S1S^{2k+1}\times S^1 be the product of an odd-dimensional sphere with a circle, and let CC be a threefold. An l.c.s. pair is a pair (ω,J)(\omega,J) consisting of a locally conformally symplectic form ω\omega and a compatible almost-complex structure JJ.

Holomorphic Seifert–Weinstein conjecture. For any l.c.s. pair (ω,J)(\omega,J) on S2k+1×S1S^{2k+1}\times S^1 or on C×S1C\times S^1 for CC a threefold, there is an elliptic, non-constant JJ-holomorphic curve.

The claim proposes removing the delta-nearby hypothesis from the preceding existence theorem. It is motivated by the existence of Reeb orbits, and hence Reeb tori, in the standard odd-dimensional sphere and for contact structures on threefolds, but the general assertion is left as a conjecture.
