In this article, we study the statistical N, sm, tn convergence, strongly Riesz convergence, Riesz statistical convergence concepts for double real number sequences. We also compare the concepts of deferred Riesz convergence, strongly deferred Riesz convergence, deferred Riesz statistical convergence for double sequences as related to the J2p−power series method. As an application, a Krovkin’s type approximation theorem related to this method is given.
