高秩的Virasoro代数的中心扩张

The Central Extensions of the Higher Rank Virasoro Algebras

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.
