A class of black holes in dRGT massive gravity and their thermodynamical
  properties
  We present exact spherical black hole solutions in de Rham, Gabadadze and
Tolley (dRGT) massive gravity for a generic choice of the parameters in the
theory, and also discuss the thermodynamical and phase structure of the black
hole in both the grand canonical and canonical ensembles (for charged case). It
turns out that the dGRT black hole solutions includes the known solutions to
the Einstein field equations, such as, the monopole-de Sitter-Schwarzschild
ones with the coefficients for the third and fourth terms in the potential and
the graviton mass in massive gravity naturally generates the cosmological
constant and the global monopole term. Furthermore, we compute the mass,
temperature, and entropy of dGRT black hole solutions and also perform
thermodynamical stability. It turns out that the presence of the graviton mass
completely changes the black hole thermodynamics, and it can provide the
Hawking-Page phase transition which is also true for the obtained charged black
holes. Interestingly, the entropy of a black hole is unaffected and still obeys
area law. In particular, our results, in the limit $m_g \rightarrow 0$, reduced
exactly to \emph{vis-$\grave{a}$-vis} the general relativity results.
