Topological spaces admitting a unique fractal structure. (English) Zbl 0832.28011
Summary: Each homeomorphism from the $$n$$-dimensional Sierpiński gasket into itself is a similarity map with respect to the usual metrization. Moreover, the topology of this space determines a kind of Haar measure and a canonical metric. We study spaces with similar properties. It turns out that in many cases, “fractal structure” is not a metric but a topological phenomenon.
