  Article:   APPROXIMATION BY MAX-PRODUCT LAGRANGE INTERPOLATION OPERATORS.

Authors:  .
 
       
         
  Abstract:  

The aim of this note is to associate to the Lagrange interpolatory polynomials on various systems of nodes (including the equidistant and the Jacobi nodes), continuous piecewise rational interpolatory operators of the so-called max-product kind, uniformly convergent to the function f, with Jackson-type rates of approximation.

Mathematics Subject Classification (2010): 41A05, 41A25, 41A35.

Keywords: Nonlinear Lagrange interpolation operators of max-product kind, equidistant nodes, Jacobi nodes, degree of approximation.
