Poincaré Gauge Theory for Gravitational Forces in (1+1) Dimensions

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 d...

Summary: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.
