Codazzi Equations

The structure equations for a two-dimensional manifold are introduced and two results based on the Codazzi equations pertinent to the study of isometric surfaces are obtained from them. Important theorems pertaining to isometric surfaces are stated and a theorem due to Bonnet is obtained. A transformation for the connection forms is developed. It is proved that the angle of deformation must be harmonic, and that the differentials of many of the important variables generate a closed differential ideal. This implies that a coordinate system exists in which many of the variables satisfy particular ordinary differential equations, and these results can be used to characterize Bonnet surfaces.

Less favorable evaluations of women physical education majors than of home economics majors, especially by men ( N = 141), in a previous study ( N = 268), led to expectations for differential Ideal Male and Ideal Female trait assignments to the two targets in this research. The expected tendency was found among this sample ( N = 217), especially among men ( N = 90).
