On absolutely almost convergence
In this paper, we study (Pn, s)-absolutely almost convergence where npn = 0(Pn) as n › ?,Pn = Pn ?n v=0 pv and s > 0. We also give necessary and sufficient conditions for a summability matrix to be (?n, s)-absolutely almost conservative, and obtain some inclusion results. © 2017, Sciendo. All rights reserved.
