摘要 利用相空间方法研究具有N个标量场的多重指数势的phantom动力学模型.特别地,作者详细研究了N=2的phantom宇宙学,指出在给定势的条件下允许存在bigrip吸引子. We study the dynamics of phantom model with multi -exponential potential which has Nscalar fields by using phase space method. Especially, in this paper, we show that big rip attractors would exist in a given potential with the case of N = 2 phantom models.
