Inverse Limits With Set-valued Functions Having Graphs That Are Arcs

Abstract

Banič and Kennedy (2015) [8] have drawn attention to a natural but largely unexplored field of study in the theory of inverse limits with set-valued functions, namely using bonding functions having graphs that are arcs. At the end of that paper they pose a question: If f:[0,1]→2[0,1] is an upper semi-continuous function such that G(fn) is connected for each n and G(f) is an arc, is lim←f connected? In this paper we provide a negative answer to that question, include some additional examples as well as a theorem on trivial shape (not requiring that the graphs be arcs), and pose several questions concerning, for the most part, inverse limits with set-valued functions whose graphs are arcs.
