Hypersurface homogeneous and hypersurface self-similar models

Classical and Quantum Gravity, 1997
The field equation for hypersurface homogeneous models and hypersurface self-similar models in terms of variables associated with the symmetry surface are presented. In terms of these variables expressions are given for the kinematical quantities associated with the perfect fluid.

Separation of hypersurfaces

Journal of Geometry, 1997
Let \(M\) be an embedded compact hypersurface in \(\mathbb{R}^{n+1}\), by \(G_M\) one denotes the Gauss map of \(M\), \(G_M: M\to S^n\). For \(M\), \(N\), two embedded, compact hypersurfaces in \(\mathbb{R}^{n+1}\) the author shows that if \(M^{[n]}=N^{[n]}\), then \(M= N\), where \[ M^{[n]}= \{p\in M:\text{rank }DG_M(p)= n\},\text{ resp. } N^{[n]}=\{p\

Transnormal hypersurfaces

Mathematical Proceedings of the Cambridge Philosophical Society, 1973
Let M be a C∞ manifold smoothly embedded as a convex hypersurface of Euclidean n-space n. M has constant width if the distance between each pair of parallel supporting hyperplanes in n is equal. This is equivalent to the condition that any chord of M normal to M at one end-point be normal to M at both end-points.
