Abstract:
We consider infinitesimal deformations of a closed surface with positive Gaussian curvature, under which the  variation of Gaussian curvature is given as a function on a surface and the Grassman image is kept invariant.

Keywords: ovaloid, Grassman image, Gaussian curvature, infinitesimal deformations, rigidity
