摘要：

In this paper we investigate coincidence and common fixed point results under order homotopies of families in preordered b-metric spaces. We first introduce the notion of selective isotone for two set-valued mappings in a complete b-metric space X. We prove some coincidence and common fixed point theorems on the preservation of the property of a family of set-valued mappings to have a common fixed point by an order homotopy.
