Phys. Rev. D 36, 1691–1700 (1987)Attempt at a classical cancellation of the cosmological constantReceived 9 April 1987; published in the issue dated 15 September 1987 I examine some classical models for a relaxing cosmological constant. The relaxation occurs by means of a classical field which ‘‘rolls’’ down a potential hill. I suggest a feedback mechanism in which the action of this field depends upon the scalar curvature of space-time. It is shown that Λeff can fall off faster than the red-shifting radiation density. There are problematic side effects associated with baryonic matter. I discuss these and possible treatments. © 1987 The American Physical Society URL:
