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

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}.
