On approximation of functions by positive linear operators

Abstract


The aim of the present paper is to point out basic results concerning the approximation of functions by using linear positive operators. We indicate the main research directions of this field and some of the most remarkable results obtained in the last half-century. Our presentation will bring to light classical and recent results in Korovkin-type approximation theory, obviously just as much as it can be done in a fewpages.
