چکیده
|
We study the convergence of the laurent polynomials of lagrange interpolation on the unit circle for continuous functions satisfying a condition about their modulus of continuity. the novelty of the result is that now the nodal systems are more general than those constituted by the n roots of complex unimodular numbers and the class of functions is different from the usually studied. moreover,some consequences for the lagrange interpolation on [-1,1] and the lagrange trigonometric interpolation are obtained. copyright © 2012 e. berriochoa et al.
