A Derivation Of The Scalar Propagator In A Planar Model In Curved Space

Abstract

Given that the free massive scalar propagator in 2 + 1 dimensional Euclidean space is $D(x-y)=\frac{1}{4\pi \rho }0.25cm{e}^{-m\rho }$ with ${\rho }^2=(x-y{)}^2$ we present the counterpart of $D(x-y)$ in curved space with a suitably modified version of the Antonsen - Bormann method instead of the familiar Schwinger - de Witt proper time approach, the metric being defined by the rotating solution of Deser et al. of the Einstein field equations associated with a single massless spinning particle located at the origin.
