Description
Summary:In this paper, evolving wormholes in the context of braneworld scenario are investigated. We have studied the possible dynamic solutions with different forms of Ricci scalar. The possibility of the existence of dynamic traversable wormholes, without resorting to an exotic matter, has been studied. By using the fact that the Einstein field equations are modified in 3 + 1 dimensions due to the brane corrections, we investigate the exact solutions which satisfy the null energy condition. Asymptotic flatness is an important property of these solutions. We discuss some physical and mathematical properties of the solutions.
