Some applications of fixed point results for monotone multivalued and integral type contractive mappings.

The motivation of the present paper is to introduce and establish some new fixed point results for monotone multivalued functions in partially ordered complete D ∗ -metric spaces, where the partial ordered set (X , ≤) is obtained via a pair of functions (ϒ , Ω) . Moreover, several existence and uniqueness coupled fixed point theorems of mappings satisfying contractive conditions have been investigated and verified in the setting of partially ordered complete D ∗ -metric spaces by using the concept of integral type contractions with respect to partially ordered D ∗ -metric space. Furthermore, we present appropriate examples as an application for our main results. Our results generalize the work of Ghasab, Majani, and Rad on the study of integral type contraction and coupled fixed point theorems in the ordered G-metric spaces. [ABSTRACT FROM AUTHOR]
