چکیده In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the ve-dimensional bulk graviton is considered to be massive. The ve dimensional nonlinear ghost-free massive gravity theory a ects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical symmetry on the brane, the full eld equations together with the generalized Israel-Darmois junction conditions on the brane and their weak eld limits are presented in details. Generally, the theory has four Stuckelberg elds along with the components of physical metric. Although analytical solutions of these equations are impossible in general, by considering some simplifying assumptions, two classes of four-dimensional spherically symmetric solutions on the brane with di erent background Stuckelberg elds are obtained
