چکیده
|
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.
