Abstract:

In this paper we study a class of upper semi-continuous multifunctions with a unique set-valued point on compact interval. By classifying the monotonicity on each subinterval, we give a completed relation between the coordinate of the set-valued points and their n-th iteration. Moreover, our method is available for the upper semi-continuous multifunctions with finitely many set-valued points, as well as those ones defined on the whole real line.

Key words: Iteration, Multifunction, Upper semi-continuous, Set-valued point, Monotonicity
