Finiteness conjecture for nontrivial Floer cohomology in a Weinstein family

Let LXL\subset X be a Lagrangian submanifold. In a Weinstein neighborhood, identify a neighborhood of the zero section in TLT^*L, and for uu in a small neighborhood of 00 in H1(L;R)H^1(L;\mathbb R) let L(u)L(u) be the graph of a closed one-form representing uu.

Finiteness conjecture for Weinstein deformations. Suppose QHb(X;Λ)QH_{\frak b}(X;\Lambda) is semi-simple. Then there exist only finitely many uu for which there exists bMweak(L(u);b)b\in\mathcal M_{\rm weak}(L(u);\frak b) such that

HF((L(u),b),(L(u),b);Λ)0.HF((L(u),b),(L(u),b);\Lambda)\ne0.

This predicts that semisimplicity restricts a fixed Lagrangian's nearby Weinstein deformations with nonzero self-Floer cohomology to a finite set. The supplied text gives no resolution status.
