Abstract
Topological conjugacy between multifunctions plays an important role in the research of dynamical systems. This paper deals with conjugacies of strictly increasing and upper semicontinuous multifunctions on a closed interval with finite set-valued points. All conjugacies between these two multifunctions are constructed with an extension method. The \(C^{1}\) smoothness of the conjugacies is also given. Moreover, an example is presented to illustrate the applications of the main results.
