Some properties of the operators defined by Lupaș
Keywords:orthogonal polynomials, spectral method, error estimate, condition number, programming, Lupas operator
AbstractIn the present paper, we show that a subclass of the operators defined by Lupaș  preserve properties of the modulus of continuity function and Lipschitz constant and the order of a Lipschitz continuous function. We are also concerned with the monotonicity of a sequence of such operators for convex functions.
