The goal of this paper is to obtain sufficient and (different) necessary conditions for a series , which is absolutely summable of order by a triangular matrix method , , to be such that is absolutely summable of order by a triangular matrix method . As corollaries, we obtain two inclusion theorems.

  • Triangular Matrix
  • Factor Theorem
