Abstract

‎ ‎Let $(\tilde{X},p)$ be the universal covering space of a compact metrizable space $X$‎, ‎which is compact and locally path connected‎.
‎In this paper‎, ‎we show that there exist metrics $d$ and $d'$ for $X$ and $\tilde{X}$‎, ‎respectively‎, ‎such that any contractive map ‎$f:X\to X$ induces a contractive map on $\tilde{X}$. ‎As an‎ application‎, ‎it is obtained that every iterated function system(IFS) on the space $X$ with attractor $K$‎, ‎induces an IFS on $\tilde{ X}$ with attractor $\tilde{K},$ such that $p(\tilde{K})=K$‎.
