从李代数的观点看角动量代数

Angula momentum recast in the formalism of Lie algebra

从李代数的观点来阐明角动量代数的一些基本内容,从而建立起纯数学表述与通常表述之间的联系,并澄清了文献中的许多混淆与不清.

Some basic aspects of angular momentum algebra are clarified from the point of view of the Lec algebra, resulting in the establishment of the relationship between pure mathematical representatious and common representations. Numurous confusions and vagueness in literatures are thus cleared up.
