摘要：
A metric based on the simplest nonlinear Lagrangian, which is identified with the square of the scalar curvature R, is considered. The region where the metric is dominated by this Lagrangian is assumed to be confined to the vicinity of the gravitational source where gravity is strongest. Expressions for R and the metric are obtained as functions of the radial distance, exhibiting nonsingular solutions.
