On the total mean curvature of a nonrigid surface
V. A. Alexandrov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
Using the Green's theorem we reduce the variation of the total mean curvature of a smooth surface in the Euclidean 3-space to a line integral of a special vector field, which immediately yields the following well-known theorem: the total mean curvature of a closed smooth surface in the Euclidean 3-space is stationary under an infinitesimal flex.
Keywords:
infinitesimal flex, vector field, flux of a vector field, circulation of a vector field, Green's formula.
