simultaneous approximation
Naokant Deo
Abstract
In this paper we give the direct and inverse theorems for
Sz\^{a}sz-Lupas operators and study the simultaneous approximation
for a new modification of the Sz\^{a}sz operators with the weight
function of Lupas operators.
Keywords: Linear positive
operators, linear combination, integral modulus of smoothness,
Steklow means.
