Nonminimal Derivative Coupling and the Recovering of Cosmological Constant

arXiv:gr-qc/9901051 · doi:10.1023/A:1026631531309

Abstract

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.
