The Voronovskaya theorem for some linear positive operators in exponential weight spaces

L. Rempulska, M. Skorupka

Resum


In this note we give the Voronovskaya theorem for some linear positive operators of the Szasz-Mirakjan type defined in the space of functions continuous on $\left[0,+\infty \right)$ and having the exponential growth at infinity.

Some approximation properties of these operators are given in \cite{3}, \cite{4}.
