Non-trivial 2+1-Dimensional Gravity

D. R. Grigore, G. Scharf

We analyze 2+1-dimensional gravity in the framework of quantum gauge theory. We find that Einstein gravity has a trivial physical subspace which reflects the fact that the classica…

From massive gravity to modified general relativity II

D. R. Grigore, G. Scharf

We continue our investigation of massive gravity in the massless limit of vanishing graviton mass. From gauge invariance we derive the most general coupling between scalar matter a…
