Özet
Throughout this paper, K denotes a complete, non-trivially valued, ultrametric (or non-archimedean) field. 4-dimensional infinite matrices, double sequences and double series have entries in K. In this paper, we prove a theorem on summability factors for the N¨orlund method for double series in K
