The Calabi–Yau critical-value conjecture

Let XX be a symplectic manifold, let bHeven(X;Λ0)\frak b\in H^{\rm even}(X;\Lambda_0) be a bulk class, and let Crit(X,st,b)\operatorname{Crit}(X,\operatorname{st},\frak b) be the set of bulk-deformed potential values arising from st\operatorname{st}-relatively spin Lagrangians with nonzero self-Floer cohomology.

Calabi–Yau critical-value conjecture. If c1(X)=0c^1(X)=0, then

Crit(X,st,b)={0}.\operatorname{Crit}(X,\operatorname{st},\frak b)=\{0\}.

This predicts that in the Calabi–Yau case the only such critical value is zero. The supplied text gives no resolution status.
