Abstract
In this paper we introduce a new type of folding called equi-Gaussian curvature folding of connected Riemannian 2-manifolds. We prove that the composition and the cartesian product of such foldings is again an equi-Gaussian curvature folding. In case of equi-Gaussian curvature foldings, f: M → P n , of an orientable surface M onto a polygon P n we prove that
and we generalize (iii) for #nT 2.
