Discussion on “Multidimensional Coincidence Points” via Recent Publications

Abstract EN

We show that some definitions of multidimensional coincidence points are not compatible with the mixed monotone property.

Thus, some theorems reported in the recent publications (Dalal et al., 2014 and Imdad et al., 2013) have gaps.

We clarify these gaps and we present a new theorem to correct the mentioned results.

Furthermore, we show how multidimensional results can be seen as simple consequences of our unidimensional coincidence point theorem.
