Splitting theorems in presence of an irrotational vector field
Manuel Gutierrez, Benjamin Olea
Abstract
New splitting theorems in a semi-Riemannian manifold which admits an irrotational vector field (not necessarily a gradient) with some suitable properties are obtained. According to the extras hypothesis assumed on the vector field, we can get twisted, warped or direct decompositions. Some applications to Lorentzian manifold are shown and also S1× L type decomposition is treated.
