使用动力系统技术分析均匀且各向同性耗散流体的演化。耗散由体粘性压力驱动，并使用截断的 Israel-Stewart 理论。尽管几乎所有解都会膨胀，但我们表明，由于不满足主要能量条件，因此只有少数解可以被视为物理解。
The evolution of an homogeneous and isotropic dissipative fluid is analyzed using dynamical systems techniques. The dissipation is driven by bulk viscous pressure and the truncated Israel-Stewart theory is used. Although almost all solutions inflate, we show that only few of them can be considered as physical solutions since the dominant energy condition is not satisfied.
