Noninclusion theorems: some remarks on a paper by J. A. Fridy
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.

| Summary: | 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. |
