Lie Algebra and Representation of SU(4)

摘要

In this paper we give a new representation for the Lie unimodular group SU(4). Boththe nonzero structure constant fkμν and the symmetric invariant tensor dkμν one calculated.We also bring out a new representation of SU(4) in terms of Pauli matrices constructed. Finally,the weight of the first fundamental representation of SU(4) is also obtained.
