论文摘要
经典的时空通常用无限多种自由度的可区分流形来描述。不过，有时候，考虑一个近似值的自由度是有限的。这样的时空有几种离散的模型，其中一些已用于构建黑洞的（简化）表示。我们将很快重新访问这些离散的黑洞模型。然后，我们将自己限制在一个特定案例中，并显示如何被量子物质领域居住。建议将场动力学描述为离散典型演化的框架，我们指出了这种方法的一些最重要的含义。
The classical spacetime is usually described by a differentiable manifold with infinitely many degrees of freedom. Occasionally though, it is useful to consider an approximation whose number of degrees of freedom is finite. There are several discrete models of spacetime like that, some of which have been used to build a (simplified) representation of a black hole. We will shortly revisit these discrete black hole models. Then we limit ourselves to one particular case and show how it can be inhabited by quantum matter fields. It is suggested that the field dynamics should be described by the framework of discrete canonical evolution, and we point out some of the most significant implications of this approach.
