Resumen:
In this work we analyze the approximation error in Sobolev norms for quasi-interpolation operators inspline spaces. We establish in a general way the hypotheses on a quasi-interpolant to achieve the optimal order of approximation. Finally, we propose simple but general constructions of such operators that satisfy the established hypotheses and illustrate their performance through some numerical tests.
