Homeomorphic classification of certain inverse limit spaces with open bonding maps

William Thomas Watkins

Vol. 103 (1982), No. 2, 589–601
Abstract

Let I = [0,1]. Let Nf be the N-th degree hat function from I to I. For example, 2f, 3f, and 4f are pictured below:



We are interested in classifying the spaces which are inverse limits of the unit interval using these bonding maps. In particular, for a fixed integer N 2, we are interested in classifying (up to homeomorphism) the space DN, which is lim
←−{I,Nf}. The main result of this paper is:

Theorem: DN is homeomorphic to DM if and only if M and N have the same prime factors.
