• Necessary and sufficient conditions for inclusion relations for absolute summability

We obtain a set of necessary and sufficient conditions for$$\left| {\bar N, p_n } \right|_k$$ to imply$$\left| {\bar N, q_n } \right|_s$$ for 1 &lt;k ≤ s &lt; ∞. Using this result we establish several inclusion theorems as well as conditions for the equivalence of$$\left| {\bar N, p_n } \right|_k$$ and$$\left| {\bar N, q_n } \right|_s$$.
