Abstract

We study a subclass of GLPV modified gravity theories generated by a general disformal metric ${\bar{g}}_{\mu \nu }={g}_{\mu \nu }+D(\phi,\partial \phi ){\partial }_{\mu }\phi {\partial }_{\nu }\phi $. By analyzing the background evolution equation, we have found that such theory cannot provide the self-accelerating solution.
