| 摘 要： | 从线形代数的图解方法出发,对自旋接网圈的数学基础做出回顾,并重新推证了圈算符和双元恒等式,计算了关于自旋接网圈的一些计算公式.还将这种方法与缠结理论做了比较;要描述圈量子引力的动力学过程,需要新的模型,自旋接网圈的因果演化模型就是其中的一种.对这种模型做了详细的探讨,对演化的两种规则作出了解释.

| Abstract: | Starting with diagrammatic methods in linear algebra,this paper reviews the mathematical basis for spin networks,proves again loop operator and binor identity,and computes some formulas about spin networks.Also it compares that method with knot theory.A new model such as the causal evolution model of spin networks is needed to describe a dynamics process of loop quantum gravity.This paper discusses the model in detail,interprets the two rules on evolution,and makes a further argumentation for causality of the model. |
