ABSTRACT
The current article deals with a modification of the Post-Widder operators which reproduce
the exponential functions both elx and e2lx for l > 0: The central moments, uniform conver-
gence of the operators and the rate of convergence of these operators with the help of
modulus of continuity are estimated. Also, a Voronovskaja-type asymptotic formula is estab-
lished. After that, numerical results are obtained to confirm the theoretical results. Finally,
new constructed operators are compared with modified Post-Widder operators.
