摘要
In this paper, for the highest weight module V(4) of sl(2,C) with the highest weight 4, we describe subalgebras S(beta)(V(4))(circle minus)+ and S(gamma)(V(4))(circle minus)+ of the beta gamma-system coset S(V(4))(circle minus)+ by giving their generators. These coset subalgebras are interesting, new examples of strongly finitely generated vertex algebra.
