The foundation representation of the Lie superalgebra su(1,1|2)×su(1,1|2)
【摘要】 目的构造su(1,1|2)×su(1,1|2)李超代数的基础表示。方法构造8×8的矩阵,利用su(1,1|2)李超代数的γ矩阵和电荷共轭矩阵C,C′分别给出su(1,1 |2)和su(1,1|2)的基础表示,然后将二者的生成元的表示做一定的组合,构造出su(1,1|2)×su(1,1|2)李超代数的基础表示。结果正确地构造出了su(1,1|2)×su(1,1|2)李超代数的基础表示,证明了该李超代数是自洽的。结论对AdS3×S3背景中Green-Schwarz IIB超弦的进一步研究具有重要意义。
【Abstract】 Aim To construct the foundation representation of the Lie superalgebra su(1,1|2)×su(1,1|2). Methods First,the foundation representations of the Lie superalgebras su(1,1|2) and su(1,1|2) were constructed by using the y matrix and the charge conjugation matrix C and C′of the Lie superalgebra su(1,1|2) with the 8×8 matrix.Then the representation of the Lie superalgebra su(1,1|2)×su(l,l|2) was given by doubling the representation of the generators of the two superalgebras su(1,1|2 and su(1,1|2) correcdy.Results The foundation representation of the Lie superalgebra su(1,1|2)×su(l,l|2) was constructed correctly and also proved that the superalgebra is self-consistent.Conclusion Given the explicit representation of the Lie superalgbra su(1,1|2)×su(1,1|2) has a great significance for the study of the Green-SchwarzⅡB superstring on AdS3×S3 background.
