SU(N)各向同性连续Heisenberg模型的延拓结构和Kac-Moody代数

PROLONGATION STRUCTURE AND KAC-MOODY ALGEBRA FOR THE SU(N) ISOTROPIC CONTINUOUS HEISENBERG MODEL

本文证明SU(N)各向同性连续Heisenberg模型在延拓结构的埋论框架内,可以由一个不完备的Kac-Moody代数生成.

It is shown that the SU(N) isotropic continuous Heisenberg model can be generated from an incomplete Kac-Moody alge- bra in the framework of the polongation structure.
