In this chapter, we will examine in more detail the representations of simple Lie algebras introduced in Sect. 13.3 and characterize all irreducible representations. In Chap. 14 , we saw that every representation D of a Lie group G induces a representation \(\mathfrak {D}\) of its Lie algebra \(T_eG\) , and the reverse is achieved through the exponential mapping.

摘要

In this chapter, we will examine in more detail the representations of simple Lie algebras introduced in Sect. 13.3 and characterize all irreducible representations. In Chap. 14 , we saw that every representation D of a Lie group G induces a representation \(\mathfrak {D}\) of its Lie algebra \(T_eG\) , and the reverse is achieved through the exponential mapping.
