Re-Scaling of Energy in the Stringy Charged Black Hole Solutions using Approximate Symmetries

Abstract

This paper is devoted to study the energy problem in general relativity using approximate Lie symmetry methods for differential equations. We evaluate second-order approximate symmetries of the geodesic equations for the stringy charged black hole solutions. It is concluded that energy must be re-scaled by some factor in the second-order approximation.
