An application of almost convergence in approximation theorems. (English) Zbl 1252.41022

Summary: The concept of almost convergence was introduced by G. G. Lorentz [Acta Math., Uppsala 80, 167–190 (1948; Zbl 0031.29501)] has various applications. In this work, we apply this method to prove some Korovkin-type approximation theorems.
