Dynamical Symmetry Breaking of Gauge Theories in Critical Situations and Space-time Structure

在高温、高密度、强曲率和紧致时空的极端情况下，研究了规范理论中的动力学对称性破缺及其对时空结构的贡献。我已经指出了维度正则化对于一个有效的理论的有效性，并发现了具有很大正则化依赖性的现象。它为我们判断适用有效理论的适当情况提供了一些预测。

Dynamical symmetry breaking in the gauge theory and its contribution to the space-time structure have been investigated under extreme circumstance, i.e.high temperature, high density, strong curvature and compact space-time. I have pointed out the usefulness of the dimensional regularization for an effective theory and found phenomena with a large regularization dependences. It gives us some predictions to judge the suitable circumstance to apply the effective theory.
