Abstract
Our aim in the present article is to introduce and study the relation between the deformation retract of the Reissner-Nordstrom spacetime N4 and the deformation retract of the tangent space Tp (N4). Also, this relation discussed after and before the isometric and topological folding of N4 into itself. New types of conditional folding are presented. Some commutative diagrams are obtained.
