Statistical korovkin theorems on abstract spaces

Let X be a Haussdorff space provided with the uniform structure (X,U). Let F be a vector space of real-valued functions defined on X including the constant-valued functions, Assume further that Y is a compact subspace of X and that {L_n} is a sequence of positive linear operators of F into R^Y. In this thesis, we obtain an abstract Korovkin-type approximation theorem in statistical sense. Then, by displaying some significant applications, we show that our approximation is more applicable and powerful than the classical ones. Furthermore, we extend our results to the multivariate function spaces.
