摘要：

We compute quantum corrections to the Raychaudhuri equation by replacing classical geodesics with quantal (Bohmian) trajectories and show that they prevent focusing of geodesics and the formation of conjugate points. We discuss implications for the Hawking-Penrose singularity theorems and curvature singularities.
