On the Deformation Retract of Kerr Spacetime and Its Folding

الملخص EN

The deformation retract of the Kerr spacetime is introduced using Lagrangian equations.

The equatorial geodesics of the Kerr space have been discussed.

The retraction of this space into itself and into geodesics has been presented.

The deformation retract of this space into itself and after the isometric folding has been discussed.

Theorems concerning these relations have been deduced.
