Poincaré Gauge Theory for Gravitational Forces in (1+1) Dimensions
arXiv:hep-th/9302026 · doi:10.1006/aphy.1993.1058
Abstract
We discuss in detail how string-inspired lineal gravity can be formulated as a gauge theory based on the centrally extended Poincaré group in $(1+1)$ dimensions. Matter couplings are constructed in a gauge invariant fashion, both for point particles and Fermi fields. A covariant tensor notation is developed in which gauge invariance of the formalism is manifest.
