Abstract

The purpose of this paper is to explore properties of the whisker topology, which is a topology endowed on the fundamental group and whose utility is to detect locally complicated phenomena in pathological topological spaces. We show that the whisker topology preserves products, resolve an open question regarding the existence of a space which makes π1wh(X,x0)\pi_1^{wh}(X,x_0) a non-discrete, non-abelian, and Hausdorff topological group, and show the whisker topology is not separable on the earring group π1(\Er1,x0)\pi_1(\Er^1,x_0).
