The monodromy conjecture for relatively exact Lagrangians

About 2 years old · traced to

Let MM be a compact or Liouville symplectic manifold, and let L⊆ML\subseteq M be a compact, relatively exact Lagrangian. Let ϕ~:L→L\tilde\phi:L\to L be a diffeomorphism extending to a Hamiltonian diffeomorphism ϕ:M→M\phi:M\to M. Monodromy conjecture. The diffeomorphism ϕ~\tilde\phi is isotopic to the identity. This would strengthen known constraints on Hamiltonian extensions, which act trivially on various cohomological and homotopical invariants of LL.
