One-Loop Vilkovisky-DeWitt Counterterms for 2D Gravity plus Scalar Field Theory


The divergent part of the one-loop off-shell effective action is computed for a single scalar field coupled to the Ricci curvature of 2D gravity (cφR), and self interacting by an arbitrary potential term V (φ). The Vilkovisky-DeWitt effective action is used to compute gauge-fixing independent results. In our background field/covariant gauge we find that the… (More)
