Causal transformation of Gödel-type space-times in conformal field theory
arXiv:1009.4784 · doi:10.1142/S0217732310034213
Abstract
The Gödel-type metrices are considered as backgrounds of the sigma-models. In the conformal field theory such backgrounds are deformed by the exactly marginal operators. We examinate, how the closed time-like curves (CTC's) transform under such deformations.
