Abstract :
In the present paper, we compute the conservation laws
of the Vaidya-Bonner geodesic space-time metric in a Riemannian
space and carry out the moving frame method for this metric. We
obtain the connection forms and curvature 2-forms, using the first
and second Cartan’s structure equations. Finally, the Ricci scalar
tensor and the components of Einstein curvature are calculated.
