Arnold-type cuplength conjecture for Lagrangian intersections
Arnold-type cuplength conjecture for Lagrangian intersections
Let be a symplectic manifold, and let and be Lagrangian submanifolds of . Assume that is either closed or a Liouville manifold, and that is connected, closed, and relatively exact, meaning
Write for the minimal number of critical points of any smooth map . Arnold-type Lagrangian intersection conjecture. There is a lower bound
This is a nontransverse version of the Arnold conjecture for Lagrangian intersections. The transverse case admits lower bounds from Floer homology, while the stated bound is formulated under relative exactness to exclude disc and sphere bubbling.
