ANNOTATION
In this paper, for classes of functions , we difine the convex modul of continuity and and find the exact tops of approximation of continuous functions by bilinear interpolation splines-functions of odd order in both variables in the uniform metric.
KEY WORDS
bilinear splines, continuity modules, upper bounds for the approximation.
