Renormalization of Quantum Gravity with Lagrange Multiplier Fields
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We study the renormalization of Einstein gravity coupled to a scalar field in the Lagrange multiplier (LM) formulation, where a pair of quantum LM fields, , is couple…

Supergravity with Lagrange Multiplier Fields in 2 + 1 Dimensions
D. G. C. McKeon, F. T. Brandt, J. Frenkel +1
We examine the first-order Einstein-Cartan (EC) action in 2+1 dimensions, including a cosmological term and its supersymmetric extension. In this setting the spin connection can be…
