# A new proof of the positive energy theorem

@article{Witten1981ANP, title={A new proof of the positive energy theorem}, author={Edward Witten}, journal={Communications in Mathematical Physics}, year={1981}, volume={80}, pages={381-402} }

A new proof is given of the positive energy theorem of classical general relativity. Also, a new proof is given that there are no asymptotically Euclidean gravitational instantons. (These theorems have been proved previously, by a different method, by Schoen and Yau.) The relevance of these results to the stability of Minkowski space is discussed.
