| 英文摘要 | We show the direct analogy between the ghost-free non-linear formulation of massive gravity and the standard sigma-models well understood in the literature. This issue explains why there are two non-trivial family of solutions for the spherically symmetric case inside the non-linear massive gravity formulations with two free parameters alpha and beta. In general, the case beta < alpha(2) has a single physical vacuum state. On the other hand, the case beta = alpha(2) contains a natural vacuum degeneracy. This is in perfect analogy with the sigma-model for scalar fields where depending on the values taken by the parameters of the theory the vacuum can be single or degenerate.
