Abstract: We consider the Picard operators $\mathcal{P}_n$ and $\mathcal{P}_{n;r}$ in exponential weighted spaces. We give some elementary and approximation properties of these operators.
AMSclassification: primary 41A25.
Keywords: Picard operator, exponential weighted space, degree of approximation, Voronovskaya type theorem.
