A real convexity theorem for quasi-hamiltonian actions
Florent Schaffhauser
The main result of this paper is a quasi-hamiltonian analogue of a special case of the O'Shea-Sjamaar convexity theorem for usual momentum maps. We denote by U a simply connected c…

Decomposable representations and Lagrangian submanifolds of moduli spaces associated to surface groups
Florent Schaffhauser
In this paper, we construct a Lagrangian submanifold of the moduli space associated to the fundamental group of a punctured Riemann surface (the space of representations of this fu…

Quasi-Hamiltonian quotients as disjoint unions of symplectic manifolds
Florent Schaffhauser
We show that the quotient associated to a quasi-Hamiltonian space has a symplectic structure even when 1 is not a regular value of the momentum map: it is a disjoint union of sympl…
