Stability Conditions For a Noncommutative Scalar Field Coupled to Gravity via the Positive Energy Theorem
arXiv:0910.3886 · doi:10.1063/1.3462678
Abstract
The stability requirements for a noncommutative scalar field coupled to gravity is investigated through the positive energy theorem. It is shown that for a noncommutative scalar with a polynomial potential, the stability conditions are similar to the ones for the commutative case. This result remains valid even whether the space-time has horizons.
