本文研究了无限维零温下Hubbard模型的金属-绝缘体相变。金属和绝缘解决方案的相互作用的有限范围内的共存。结果表明，金属溶液是在共存区的任何相互作用的能量较低，过渡是二级的。
We study the metal-to-insulator transition of the Hubbard model at zero temperatures in infinite dimensions. The coexistence of metallic and insulating solutions for a finite range of the interaction is established. It is shown that the metallic solution is lower in energy for any interaction in the coexistence region and that the transition is of second order.
