The degenerate Arnol'd conjecture for Hamiltonian-isotopic Lagrangians
The degenerate Arnol'd conjecture for Hamiltonian-isotopic Lagrangians
Let be a closed symplectic manifold, and let be a Hamiltonian-isotopic pair of Lagrangians. Suppose each is connected and closed, and satisfies
Here denotes the smooth real-valued functions on , and is the set of critical points of .
Degenerate Arnol'd conjecture. The intersection satisfies
This is a lower bound for possibly degenerate Lagrangian intersections, motivated by Floer homotopy theory and intended to strengthen intersection bounds in settings such as plumbings of cotangent bundles. The supplied text gives no evidence that this conjecture has been resolved.
