Chapter Chapter 5 in Convergence Methods for Double Sequences and Applications, 2014, pp 79-97 from Springer

Abstract: Abstract In this chapter, we define P-core, M-core, and R-cores by using the notion of Pringsheim’s convergence, almost convergence, and Riesz’s convergence of double sequences. We present various core theorems analogous to the well-known Knopp core theorem.
