Although their notion seems to be attractive, in this paper, we show how this concept can be reduced to the unidimensional notion of coincidence point, and how their main theorems can be seen as particular cases of existing results. Moreover, we prove that the proofs of their main statements have some gaps.eninfo:eu-repo/semantics/openAccess[No Keyword Available]ArticleQ1WOS:000349389900002
