Case %J Mathematics %D 2007 %I arXiv %R 10.1016/j.geomphys.2009.11.001 %X We consider the Hawking-Penrose singularity theorems and the Lorentzian splitting theorem under the weaker curvature condition of nonnegative Bakry-Emery-Ricci curvature $Ric_f^m$ in timelike directions. We prove that they still hold when $m$ is finite, and when $m$ is infinite, they hold under the additional assumption that $f$ is bounded from above. %U http://arxiv.org/abs/0712.1321v2
