Abstract
This paper proves that any nonregular nonparametric saddle surface in a three-dimensional space of nonzero constant curvature , which is bounded by a rectifiable curve, is a space of curvature not greater than in the sense of Aleksandrov. This generalizes a classical theorem by Shefel′ on saddle surfaces in .
