Sahin, Pinar OkcuDirik, Fadime2025-03-232025-03-2320191607-2510https://hdl.handle.net/11486/7461In this work, we introduce our new concept of the statistical equal convergence for double function sequences. Later, we introduce the concept of statistical relative equal convergence of double function sequences which is stronger than the notion of statistical relative convergence and statistical uniform convergence to demonstrate a Korovkin type approximation theorem and prove that our theorem is a non-trivial extension of some well-known Korovkin type approximation theorems which were proven by earlier authors. We present an example in support of our definition and result presented in this paper. Finally, we study Voronovskaya type theorem via statistical relative equal convergence.eninfo:eu-repo/semantics/closedAccessUniform-ConvergenceArticle191011152-s2.0-85071196670N/AWOS:000505083600010N/A
