A pseudo-Riemannian manifold endowed with multiple orthogonal complementary distributions, called a Riemannian almost multi-product structure, generalizes concepts such as multiply twisted (warped) products and Einstein equations, the webs composed of several foliations and Dupin hypersurfaces.
This talk reviews my recent results (published in arXiv) concerning the following two topics on the mixed scalar curvature of a Riemannian almost multi-product manifold: a) integral formulas and splitting of a manifold; b) action of the Einstein-Hilbert type.
