On fivedimensional massive (bi)gravity
Abstract
Main results of our recent investigations on fivedimensional scenarios of massive (bi)gravity will be summarized in this article. In particular, we will show how to construct higher dimensional massive graviton terms from the characteristic equation of square matrix, which is a consequence of the CayleyHamilton theorem. Then, we will show whether massive graviton terms of fivedimensional massive (bi)gravity behave as effective cosmological constants for a number of physical metrics compatible with fiducial ones such as the FriedmannLemaitreRobertsonWalker, Bianchi type I, and SchwarzschildTangherlini metrics. Finally, we will show the corresponding cosmological solutions for the fivedimensional massive (bi)gravity.
