Abstract
Features of the quantum field theory in the background of the Godel sp ace-time are investigated. By using the Euclidean approach, a quantum field propagating in this background is found to possess a temperature proportional to the magnitude of the cosmic vorticity. However, in th e semiclassical approximation, the Godel solution does not present an intrinsic entropy. (C) 1998 Elsevier Science B.V.
