Propagators in AdS for higher-derivative and nonlocal gravity: Heat kernel approach
Abstract We present a new covariant method of construction of the (position space) propagators in the N-dimensional (Euclidean) anti-de Sitter background for any gravitational theory with the Lagrangian that is an analytic expression in the metric, curvature, and covariant derivative. We show that t...
