Resumen de Monodromy and isotopy of monotone Lagrangian tori

Mei-Lin Yau

• We define new Hamiltonian isotopy invariants for a 2-dimensional monotone Lagrangian torus embedded in a symplectic 4-manifold. We show that, in the standard symplectic $\R^4$, these invariants distinguish a monotone Clifford torus from a Chekanov torus.
