| Abstract: | The Dyson-Schwinger equations of Landau-gauge Yang-Mills theory for the gluon and ghost propagators are investigated. Numerical results are obtained within a truncation scheme which has proven to be successful at vanishing temperature. For temperatures up to 250 MeV we find only minor quantitative changes in the infrared behavior of the gluon and ghost propagators. The effective action calculated from these propagators is temperature independent within the numerical uncertainty.Received: 25 August 2004, Revised: 29 March 2005, Published online: 8 June 2005PACS: 11.10.Wx, 12.38.Aw, 14.70.Dj |
