Fecha de publicación: | 26-may-2005 | Editor: | American Institute of Physics | Citación: | Journal of Mathematical Physics 46(6): 062306 (2005) | Resumen: | We discuss the asymptotic behavior of regulated field commutators for linearly polarized, cylindrically symmetric gravitational waves and the mathematical techniques needed for this analysis. We concentrate our attention on the effects brought about by the introduction of a physical cutoff in the study of the microcausality of the model and describe how the different physically relevant regimes are affected by its presence. Specifically we discuss how genuine quantum gravity effects can be disentangled from those originating in the introduction of a regulator. | Descripción: | 21 pages, 9 figures.-- PACS nrs.: 04.60.Ds, 04.60.Kz, 04.62.+v.-- ArXiv pre-print available at: http://arxiv.org/abs/gr-qc/0412028 | Versión del editor: | http://dx.doi.org/10.1063/1.1864251 | URI: | http://hdl.handle.net/10261/12818 | DOI: | 10.1063/1.1864251 | ISSN: | 0022-2488 |
