DOI: 10.1016/j.dark.2019.100446
Abstract: We establish an extended version of the modified Saez-Ballester (SB) scalar-tensor theory in arbitrary dimensions whose energy momentum tensor as well as potential are pure geometrical quantities. This scenario emerges by means of two scalar… read more here.
