We propose an approach to quantum cosmology of integrable models. To analyze the models with two dynamical variables, we introduce equivalent Hamiltonians in reduced phase spaces, which are obtained with the aid of the Faddeev--Jackiw method. Quantum dynamics of the models can be studied by using the equivalent Hamiltonians with various techniques.

可积模型量子宇宙学的等效哈密顿方法

我们提出了一种可积模型的量子宇宙学方法。为了分析具有两个动力学变量的模型，我们在简化的相空间中引入了等效的哈密顿量，这是借助 Faddeev--Jackiw 方法获得的。模型的量子动力学可以通过使用各种技术的等效哈密顿量来研究。
