Abstract
Our aim in the present article is to introduce and study a new type of metric, namely Reissner - Nordstrom space time metric. New types of geodesics in Reissner - Nordstrom space time are presented. The retraction of Reissner - Nordstrom space time is defined and discussed. The deformation retracts of Reissner - Nordstrom space time into itself and onto geodesics are deduced. Also, the isometric and topological folding in each case and the relation between the deformation retracts after and before folding have been obtained. New types of homotopy maps are described.
