TOPIC: Stability of the spectrum of frustration free Hamiltonians

Abstract
We generalize the proof of the stability of the spectrum for commuting Hamiltonians (frustration free Hamiltonians with commuting interactions), by removing the assumption of commutativity. We introduce the condition of Local Topological Order, which is necessary for stability under small perturbations
