摘要：
Previous papers dealt with the quantization of the Lemaitre-Tolman-Bondi (LTB) model for vanishing cosmological constant Lambda. Here we extend the analysis to the case Lambda > 0. Our main goal is to present solutions of the Wheeler-DeWitt equation, to give their interpretation and to derive Hawking radiation from them. We restrict ourselves to a discussion of those points that are different from the Lambda = 0-case. These are mainly to do with the occurrence of two horizons.
