GENERAL RELATIVITY AND SECTIONAL CURVATURE

International Journal of Geometric Methods in Modern Physics, 2006
A discussion is given of the sectional curvature function on a four-dimensional Lorentz manifold and, in particular, on the space–time of Einstein's general relativity theory. Its tight relationship to the metric tensor is demonstrated and some of its geometrical and algebraic properties evaluated.

Cross-sectional design with curvature constraints

Computer-Aided Design, 2005
A practical example of B-spline curve control points manipulation for the geometric construction of a free form shape is presented. Elements of a cross-sectional design methodology are used in conjunction with a skinning type operator for the definition of a B-spline surface.
