Abstract
Let G be a connected simply connected noncompact classical simple Lie group of
Hermitian type. Then G has unitary highest weight representations. The proof of the classi- fication of unitary highest weight representations of G given by Enright, Howe and Wallach is based on the Dirac inequality of Parthasarathy, Jantzen's formula and Howe's theory of dual pairs where one group in the pair is compact. In this paper we focus on the Dirac inequality which can be used to prove the classification in a more direct way.
