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…
Massive gravity from descent equations
D. R. Grigore, G. Scharf
Both massless and massive gravity are derived from descent equations (Wess-Zumino consistency conditions). The massive theory is a continuous deformation of the massless one.
Massive Supersymmetric Quantum Gauge Theory
Dan Radu Grigore, Markus Gut, Gunter Scharf
We continue the study of the supersymmetric vector multiplet in a purely quantum framework. We obtain some new results which make the connection with the standard literature. First…
Quantum Extended Supersymmetries
Dan Radu Grigore, Gunter Scharf
We analyse some quantum multiplets associated with extended supersymmetries. We study in detail the general form of the causal (anti)commutation relations. The condition of positiv…
The Quantum Supersymmetric Vector Multiplet and Some Problems in Non-Abelian Supergauge Theory
Dan Radu Grigore, Günter Scharf
We consider the supersymmetric vector multiplet in a purely quantum framework. We obtain some discrepancies with respect to the literature in the expression of the super-propagator…
