  We investigate the effect of massive graviton on the holographic
thermalization process. Before doing this, we first find out the generalized
Vaidya-AdS solutions in the de Rham-Gabadadze-Tolley (dRGT) massive gravity by
directly solving the gravitational equations. Then, we study the thermodynamics
of these Vaidya-AdS solutions by using the Minsner-Sharp energy and unified
first law, which also shows that the massive gravity is in a thermodynamic
equilibrium state. Moreover, we adopt the two-point correlation function at
equal time to explore the thermalization process in the dual field theory, and
to see how the graviton mass parameter affects this process from the viewpoint
of AdS/CFT correspondence. Our results show that the graviton mass parameter
will increase the holographic thermalization process.
