Tauberian theorems for the product of weighted and Cesàro summability methods of double sequences
Tauberian theorems for the product of weighted and Cesàro summability methods of double sequences
In this paper, we obtain necessary and sufficient conditions, under which convergence of a double sequence in Pring-sheim's sense follows from its weighted-Cesàro summability. These Tauberian conditions are one-sided or two-sided if it is a sequence of real or complex numbers, respectively.
