Infinitesimal Bendings of Homogeneous Surfaces with Nonnegative Curvature

摘要

This paper deals with infinitesimal bendings of a surface S in a neighborhood of a point p ? S. More precisely, consider a surface S embedded in R3 and given by parametric equation R(u, v) = (x(u, v), y(u, v), z(u, v)) ∈ R~3m (1.1)
