3+1-Dimensional GR versus dRGT massive gravity: a thin-shell wormholes comparison

Abstract

Spherically static black hole solution in vacuum GR and dRGT massive gravity with identical radius of event horizons are compared. First, we analyze the differences between the two theories in terms of some basic thermodynamics properties such as the Hawking temperature and the specific heat capacity. Then, for a more detailed comparison we construct thin-shell wormholes in both theories and study their different aspects, namely the amount of the exotic matter and the linear dynamic stability.
