Noninclusion theorems: some remarks on a paper by J. A. Fridy
W. Beekmann
International Journal of Mathematics and Mathematical Sciences, 2000, vol. 23, 1-4
Abstract:
In 1997, J. A. Fridy gave conditions for noninclusion of ordinary and of absolute summability domains. In the present note, these conditions are interpreted in a natural topological context thus giving new proofs and also explaining why one of these conditions is too weak. Also an open question posed in Fridy's paper is answered.
