The local moduli of Sasakian 3 manifolds
... The main tool used here is the Newman-Penrose-Perjes spin coefficient formalism, details of which can be found in [6]. This technique is also used to show that there are no non-Einstein conformally flat Sasakian ...

4-Manifolds With Inequivalent Symplectic Forms and 3-Manifolds With Inequivalent Fibrations
... To describe this example, we recall the correspondence between closed 1-forms and measured foliations. Let α be a closed 1-form on M, such that α and its pullback to ∂M are pointwise nonzero. Then α defines a measured ...
