Nonminimal derivative coupling and the recovering of cosmological constant
Jan, 1999Citations per year
Abstract: (arXiv)
We show that the existence of the cosmological constant can be connected to a nonminimal derivative coupling, in the action of gravity, between the geometry and the kinetic part of a given scalar field without introducing any effective potential of scalar fields. Exact solutions are given.Note:
