• Lorentzian warped products and static space-times 

    Allison, Dean Edwin (University of Missouri--Columbia, 1985)
    Let (M, g) be a Lorentzian manifold, (H, h) a Reimannian manifold, and let f: H [right arrow] (0, [infinity symbol] be an arbitarary smooth function. Then the product manifold M x H with Lorentzian metric g = (f[suprscript ...
