摘要：
A splint of a root system for a simple Lie algebra appears naturally in studies of (regular) embeddings of reductive subalgebras. A splint can be used to construct branching rules. We demonstrate that implementation of splint properties drastically simplifies calculations of branching coefficients. Bibliography: 5 titles. © 2013 Springer Science+Business Media New York.
