mean curvature in a sentence

Examples

1. For an open soap film, the pressure difference is zero, hence the mean curvature is zero, and minimal surfaces have the property of zero mean curvature.
2. For an open soap film, the pressure difference is zero, hence the mean curvature is zero, and minimal surfaces have the property of zero mean curvature.
3. The partial differential equation in this definition was originally found in 1762 by Lagrange, and Jean Baptiste Meusnier discovered in 1776 that it implied a vanishing mean curvature.
4. The first and second fundamental forms of a surface determine its important differential-geometric invariants : the Gaussian curvature, the mean curvature, and the principal curvatures.
5. If the measurement is close enough to the surface, light rays can curve downward at a rate equal to the mean curvature of the Earth's surface.
6. Barbour implemented these principles in collaboration with Niall ?Murchadha, Edward Anderson, Brendan Foster and Bryan Kelleher to derive the ADM formalism in constant mean curvature gauge.
7. Furthermore, a surface which evolves under the mean curvature of the surface S, is said to obey a heat-type equation called the mean curvature flow equation.
8. Furthermore, a surface which evolves under the mean curvature of the surface S, is said to obey a heat-type equation called the mean curvature flow equation.
9. In fact, the mean curvature across the entire surface is always the reciprocal of twice the major axis length : 1 / ( 2 " a " ).
10. More precisely, the principal curvatures and the mean curvature change the sign if the orientation of the surface is reversed, and the Gaussian curvature is entirely independent of the parametrization.
