Abstract :
In this paper, a vector version of the intermediate value theorem is established. The main theorem
of this article can be considered as an improvement of the main results have been appeared in [On
xed point theorems for monotone increasing vector valued mappings via scalarizing, Positivity, 19
(2) (2015) 333-340] with containing the uniqueness, convergent of each iteration to the xed point,
relaxation of the relatively compactness and the continuity on the map with replacing topological
interior of the cone by the algebraic interior. Moreover, by applying Ascoli-Arzela's theorem an
example in order to show that the main theorem of the paper [An intermediate value theorem for
monotone operators in ordered Banach spaces, Fixed point theory and applications, 2012 (1) (2012)
1-4] may fail, is established.
