Query: Folded Symplectic Toric Four-Manifolds   We show that two orientable, four-dimensional folded symplectic toric
manifolds are isomorphic provided that their orbit spaces have trivial
degree-two integral cohomology and there exists a diffeomorphism of the orbit
spaces (as manifolds with corners) preserving orbital moment maps.
