Contribution

It introduces a generalized framework for non-abelian orbifolds in string theory, expanding beyond previous real fermionic approaches.

Findings

Developed new rules for non-abelian orbifolds

Applied the rules to asymmetric orbifold constructions

Provided examples demonstrating the methods' effectiveness

Abstract

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.
