对于李代数sl(2,)的最高权为4的不可约表示V4,给出了βγ-系统commutantS(V4)^Θ+的一个共形向量.在共形场论中,共形向量代表了某种共形场模型保持共形对称性.
For the highest weight module V4 of sl(2,M) with the highest weight 4,this paper explicitly gived a conformal vector of the βγ-system commutant S(V4)^Θ+.In conformal field theory,a conformal vector represents some conformal symmetry in the commutant.
