摘要
给出了秩为2的高秩的Virasoro代数的中心扩张,由此可以看出高秩的Vira-soro代数的中心扩张不同于Virasoro代数的中心扩张。
Give the central extensions of the higher rank Virasoro algebras under the condition of n =2.From this,one can find that the central extensions are different from the central extension of the Virasoro algebra.By the way,the central extension of the higher rank Virasoro algebras given by 2 is only a special case.
