@article{Fewster2011SingularityTF, title={Singularity theorems from weakened energy conditions}, author={Christopher J. Fewster and Gregory J. Galloway}, journal={Classical and Quantum Gravity}, year={2011}, volume={28}, pages={125009} }

We establish analogues of the Hawking and Penrose singularity theorems based on (a) averaged energy conditions with exponential damping; (b) conditions on local stress–energy averages inspired by the quantum energy inequalities satisfied by a number of quantum field theories. As particular applications, we establish singularity theorems for the Einstein equations coupled to a classical scalar field, which violates the strong energy condition, and the nonminimally coupled scalar field, which…

The proof shows that the ANEC is a direct consequence of the general positivity condition which must hold for the two-point function of any state, and extends to establish the AN EC for the null geodesic generators of the horizon (provided that there exists a stationary Hadamard state of the field).
