The aim of the paper is to construct some univariate Bernstein-type operators on triangle, their product and Boolean sum, which interpolate a given function on the edges respectively at the vertices of triangle. Using the modulus of continuity and th

The aim of this paper is to define the elementary spline functions in analogy with the definition of the polynomial spline functions, given by I. J.Schonberg. Also, it is described a method for constructing the elementary spline functions. Finally, s
