Abstract

In this study, we establish the necessary and sufficient conditions for a four-dimensional matrix to map entire double-indexed sequences onto themselves, referring to such transformations as entire methods. Furthermore, we present a theorem addressing the consistency of these entire summation methods.

Keywords
