Generation conjecture for the HDHF wrapped Fukaya category of cotangent bundles

About 19 years old · traced to

Let QQ be a closed oriented manifold with vanishing relative second Stiefel–Whitney class, and let Wκ(T∗Q)\mathcal{W}_\kappa(T^*Q) denote its HDHF wrapped Fukaya category. A κ\kappa-tuple of cotangent fibers is a collection of κ\kappa pairwise disjoint cotangent fibers in T∗QT^*Q.

Generation conjecture. The category Wκ(T∗Q)\mathcal{W}_\kappa(T^*Q) is split-generated by any κ\kappa-tuple of disjoint cotangent fibers.

This conjecture proposes the multiple-particle analogue of the generation criterion for the wrapped Fukaya category of a cotangent bundle. The surrounding discussion suggests that algebraic structures on HFSH may help establish it, but no resolution is given here.
