Moment polytopes for symplectic manifolds with monodromy
San Vu Ngoc
A natural way of generalising Hamiltonian toric manifolds is to permit the presence of generic isolated singularities for the moment map. For a class of such ``almost-toric 4-manif…

On semi-global invariants for focus-focus singularities
San Vu Ngoc
This article gives a classification, up to symplectic equivalence, of singular Lagrangian foliations given by a completely integrable system of a 4-dimensional symplectic manifold,…
