摘要:
We present a general method for determining the structure of the gravitational equations of motion in the currently experimentally viable fourth-order theory of gravity based on local conformal Weyl invariance of the gravitational action and give the explicit structure for these equations in the case where the geometry is described by a time-dependent, spherically symmetric line element.
