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. 
Proof of the positive energy theorem including the angular momentum contribution
A proof of the positive energy theorem of general relativity is given. In this proof the gravitational Lagrangian is identified with that of Lau and is equivalent to the teleparallel Lagrangian
On Witten's proof of the positive energy theorem
This paper gives a mathematically rigorous proof of the positive energy theorem using spinors. This completes and simplifies the original argument presented by Edward Witten. We clarify the geometric
The positivity of gravitational energy and global supersymmetry
The concept of gravitational energy and the proof of its positivity are reviewed. The relationship between Witten's proof of the positivity of mass and supergravity is explained with reference to the
A remark on the positive-energy theorem
The problem of the weakest possible boundary conditions for the positive-energy theorem is discussed. Examples of asymptotically flat (in some sense) metrics violating this theorem are given. A class
A remark on the rigidity case of the positive energy theorem
In their proof of the positive energy theorem, Schoen and Yau showed that every asymptotically flat spacelike hypersurface M of a Lorentzian manifold which is flat along M can be isometrically
A strictly-positive mass theorem
We show that the ADM 4-momentum of an isolated gravitational system (spatially asymptotically flat spacetime) satisfying the dominant energy condition cannot be null-like unless it is flat. Together
Generalized theorem on positive definiteness of energy in the general relativity theory
We introduce the notion of the energy of gravitational and material fields with respect to an arbitrary time-like vector field and a space-like hypersurface as an integral over a nonholonomic


Proof of the Positive-Action Conjecture in Quantum Relativity
We extend our previous method of proving the positive-mass conjecture to prove the positive-action conjecture of Hawking for asymptotically Euclidean metric. This result is crucial in proving the
Positivity of the Total Mass of a General Space-Time
The positive-mass conjecture states that for a nontrivial isolated physical system, the total energy, which includes contributions from both matter and gravitation, is positive. This assertion has
Supergravity Has Positive Energy
We show that the total energy in supergravity theory is nonnegative. The derivation is based on the fact that for bounded systems the Hamiltonian operator is the square of the spinor supercharge just
On the proof of the positive mass conjecture in general relativity
LetM be a space-time whose local mass density is non-negative everywhere. Then we prove that the total mass ofM as viewed from spatial infinity (the ADM mass) must be positive unlessM is the flat
Canonical variables for general relativity
The general theory of relativity is cast into normal Hamiltonian form in terms of two pairs of independent conjugate field variables. These variables are explicitly exhibited and obey ordinary
The existence of maximal slicings in asymptotically flat spacetimes
We consider Cauchy data (g, π) on IR3 that are asymptotically Euclidean and that satisfy the vacuum constraint equations of general relativity. Only those (g, π) are treated that can be joined by a
The Positive Action conjecture and asymptotically Euclidean metrics in quantum gravity
The Positive Action conjecture requires that the action of any asymptotically Euclidean 4-dimensional Riemannian metric be positive, vanishing if and only if the space is flat. Because any Ricci
