| Abstract: | Two renormalization approaches:the analytic continuation approach and the subtraction approach, are used to obtain the infrared behavior of gluon and ghost propagators in the coupled gluon and ghost Dyson- Schwinger equations,where the three-gluon and gluon-ghost vertices are taken to be bare.The results show that the two renormalization approaches give the same results in the infrared analysis of propagators. |
