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.
