Abstract

Modified gravity theories have gained recently an increasing interest in cosmology since they offer some solutions to a number of cosmological puzzles. All these theories are formulated by means of one occurrence of action that group geometry and fields in one single package. In this communication, we introduce a simple modified gravity based on the occurrence of two independent actions. We show that their combination divulge some properties that bear a resemblance to induced gravity and offer new insights in astrophysics and cosmology.
