摘要：

Twisted products are generalizations of warped products, namely the warping function may depend on the points of both factors. The two canonical foliations of a twisted product are mutually perpendicular and their leaves are totally geodesic, resp. totally umbilic. The main result is a decomposition theorem of de Rham type; If on a simply connected, geodesically complete pseudo-Riemannian manifold M two foliations with the above properties are given, then M is a twisted product.
