Multiply warped products

Journal of Geometry and Physics, 2000
The author first states covariant derivative formulas for multiply warped products and considers the geodesic equations for these spaces. Then he states some basic facts about causality of Lorentzian multiply products and studies Cauchy surfaces and global hyperbolicity.

Hypersurfaces in Warped Products

2016
A classical result of Alexandrov [10] states that a compact hypersurface with constant mean curvature embedded in Euclidean space must be a round sphere. The original proof is based on a clever use of the maximum principle for elliptic partial differential equations.

Geometry of Affine Warped Product Hypersurfaces

Results in Mathematics, 2005
Let \((N_1,h_1)\), \((N_2,h_2)\) be Riemannian manifolds of positive dimensions \(n_1\), \(n_2\). If \(f\) is a positive valued function on \(N_1\), then the product manifold \(N_1\times N_2\) equipped with the warped product metric \(h_1+ f^2 h_2\) is called a warped product manifold \(N_1\times_f N_2\) with warping function \(f\).

Warped Product Lightlike Submanifolds

Sarajevo Journal of Mathematics
e study a new class of lightlike submanifolds $M$, called warped product lightlike submanifolds, of a semi-Riemann manifold. We show that the null geometry of $M$ reduces to the corresponding non-degenerate geometry of its semi-Riemann submanifold.   2000 Mathematics Subject Classification.

Warp-Knitted Semi-finished Products and Warp-Knitting Technologies

2016
The production of warp-knitted semi-finished products is based on classical warp knitting processes, in which warp yarns of one or several groups are simultaneously and parallelly transformed into loops. This basic principle is used to connect yarn layers and/or other fabrics, such as nonwovens or pre-impregnated fiber layers by means of these loops ...
