Abstract :In this work we have studied the evolution of a warped product insert ignore into journalissuearticles values(WP); manifold under second order renormalization group insert ignore into journalissuearticles values(RG-2); flow. We have shown some conditions for the existence of a solution of RG-2 flow on WP manifolds. Also, we have found a necessary condition for warped function under RG-2 flow. In particular, we study some special WP metric of real line with a manifold. Eventually, by extending conditions to pseudo-Riemannian manifold, we find a PDE for Robertson-Walker insert ignore into journalissuearticles values(RW); metrics, and show that there is no RG-2 flow for RW metrics.
