【 摘 要 】
In this paper, we consider a model of interacting phantom and Yang–Mills (YM) ï¬elds by assuming dilaton-type coupling. Using the speciï¬c solution for YM equation previously found by the author, we obtain simple exact solutions for the accelerated expansion of the Friedmann–Robertson–Walker (FRW) cosmological model. Besides, we derive induced potentials of phantom ï¬eld corresponding to some given regimes of expansion. The effective equations of state (EoS) have been reconstructed for all types of models considered here.【 授权许可】
