The degree of approximation by Chebyshevian splines Academic Article uri icon


  • This paper studies the connections between the smoothness of a function and its degree of approximation by Chebyshevian splines. This is accomplished by proving companion direct and inverse theorems which give a characterization of smoothness in terms of degree of approximation. A determination of the saturation properties is included. © 1973 American Mathematical Society.
