在一般的Robertson-Walker宇宙学中，驱动暴胀的标量场被用作动力学变量，将场方程表示为一阶微分系统。这使得对超级通货膨胀的研究得以进行。结果表明，在慢卷近似成立的情况下，在封闭宇宙学中可能发生超暴涨，并给出了一个新的超暴涨解。将这种技术扩展到比安奇模型的可能性进行了研究。
The scalar field driving inflation in a general Robertson-Walker cosmology is used as a dynamical variable to express the field equations as a first-order differential system. This allows a study of super-inflation to be made. It is found that super-innflation is likely to occur in closed cosmologies when the slow-roll approximation is valid and a new super-inflationary solution is presented. The possibility of extending this technique to the Bianchi models is examined.
