标题： Asymmetric Non-Abelian Orbifolds and Model Building

摘要： 自由费米子弦模型的构建规则被扩展以包括一般的非阿贝尔 orbifold 构造，这些构造超出了实费米子方法。 这种推广也被应用于最近引入的非阿贝尔 orbifold 规则。 这些非阿贝尔 orbifold 规则非常易于使用。 给出了例子来说明它们的应用。 显示英文摘要

摘要： The rules for the free fermionic string model construction are extended to include general non-abelian orbifold constructions that go beyond the real fermionic approach. This generalization is also applied to the asymmetric orbifold rules recently introduced. These non-abelian orbifold rules are quite easy to use. Examples are given to illustrate their applications.
