Coroianu, Lucian; Gal, Sorin G. Global smoothness preservation by some nonlinear max-product operators. (English) Zbl 1289.41001 Mat. Vesn. 64, No. 4, 303-315 (2012). Authors’ abstract: We study the problem of partial global smoothness preservation in the cases of max-product Bernstein approximation operators, max-product Hermite-Féjer interpolation operators based on the Chebyshev nodes of the first kind and max-product Lagrange interpolation operators based on the Chebyshev nodes of the second kind.
