Resumen de Construction of quintic Powell�Sabin spline quasi-interpolants based on blossoming

M. Lamnii, H. Mraoui, A. Tijini

• By blossoming Marsden�s identity, we investigate local quasi-interpolation schemes for C2-continuous quintic Powell�Sabin splines represented with a normalized B-spline basis.

  As applications, various families of discrete and differential quasi-interpolants reproducing quintic polynomials are presented.
