Hyperbolic Ricci soliton on warped product manifolds


Shahroud Azami, Ghodratallah Fasihi-Ramandi




In this paper, we investigate hyperbolic Ricci soliton as the special solution of hyperbolic geometric flow on warped product manifolds. Then, especially, we study these manifolds admitting either a conformal vector field or a concurrent vector field. Also, the question that:” whether or not a hyperbolic soliton reduces to an Einstein manifold?” is considered and answered. Finally, we obtain some necessary conditions for generalized Robertson-Walker space-time to be a hyperbolic Ricci soliton.
