Korovkin type approximation theorems obtained through generalized statistical convergence

The concept of λλ-statistical convergence was introduced in [M. Mursaleen, λλ-statistical convergence, Math Slovaca, 50 (2000) 111–115] by using the generalized de la Vallée Poussin mean. In this work we apply this method to prove some Korovkin type approximation theorems.
