不定型Kac-Moody代数ID_n(α)的结构

A Construction of Lie Algebras of Indefinite Kac－Moody

本文构造了不定型Kac－Moody代数IDn（α）的结构，为进一步研究不定型Kac－Moody代数IDn（α）的虚根系等问题打下基础。

Deals with a construction of Lie Algebras of Indefinite Kac－Moody. And provides with the basis ofproblems for a further reseach in the imaginary root system of algebras ID.(α) of indefinite Kac－Moody.
