Abstract

Let HH be a subgroup of π1(X,x0)\pi_{1}(X,x_{0}). In this paper, we extend the concept of XX being SLT space to HH-SLT space at x0x_0. First, we show that the fibers of the endpoint projection pH:X~HXp_{H}:\tilde{X}_{H}\rightarrow X are topological group when XX is HH-SLT space at x0x_0 and HH is a normal subgroup. Also, we show that under these conditions the concepts of homotopically path Hausdorff relative to HH and homotopically Hausdorff relative to HH coincide. Moreover, among other things, we show that the endpoint projection map pHp_{H} has the unique path lifting property if and only if HH is a closed normal subgroup of π1qtop(X,x0)\pi_{1}^{qtop}(X,x_{0}) when XX is SLT at x0x_{0}. Second, we present conditions under which the whisker topology is agree with the quotient of compact-open topology on X~H\tilde{X}_{H}. Also, we study the relationship between open subsets of π1wh(X,x0)\pi_{1}^{wh}(X,x_{0}) and π1qtop(X,x0)\pi_{1}^{qtop}(X,x_{0}).
