Constructibility of momentum maps and linear variation for singular symplectic reduced spaces
Maarten Mol
In this paper we show that the transverse image of the momentum map of a Hamiltonian Lie group action admits a natural integral affine stratification with the property that over ea…

On the classification of multiplicity-free Hamiltonian actions by regular proper symplectic groupoids
Maarten Mol
In this paper we study a natural generalization of symplectic toric manifolds in the context of regular Poisson manifolds of compact types. To be more precise, we consider a class…
