Equivalent Conditions for Digital Covering Maps
Abstract
It is known that every digital covering map $p:(E,\kappa)\rightarrow (B,\lambda)$ has uniqe path lifting property. In this paper, we show that its inverse is true when the continuous surjection map $p$ has no conciliator point. Also, we prove that a digital $(\kappa,\lambda)-$continuous surjection $p:(E,\kappa)\rightarrow (B,\lambda)$ is a digital covering map if and only if it is a local isomorphism. Moreover, we find out a loop criterion for a digital covering map to be a radius $n$ covering map
