Abstract

Based on the probabilistic theory, the paper contains local estimates of the rate of convergence for contraction~ $C_{0}$ -semigroup. Simultaneously a class of linear positive operators of Feller-Stancu type is introduced, and the local and global rate of convergence for continuous functions is studied.
