Abstract

In 1993, the authors presented a fixed point theorem of Meir-Keeler type. The proposed proof of a lemma-on which the said theorem depends on-is invalid. In this note, we alter the statement of this lemma and give a valid proof thereof, so that the main result of the previous paper is still true.
