Approximation via power series statistical convergence for double sequences of matrix-valued functions
K. Demirci, S. Çınar
In this study, we give an extension of Korovkin's theorem for functions
belonging to a special class. Basically, we will obtain effective results by
making use of the notion of statistical convergence in sense of the power
series method which is widely used in approximation theory. With given
example, we offer a stronger point of view than the classical meaning and we
study the the rates of PP2-statistical convergence.
