一般线性李超代数gl(2/2)的所有有限维不可约表示都被写成矩阵形式。每个表示空间内的基的选择方式使得gl(2/2)分解为其偶子代数gl(2)⊕gl(2)的不可约表示是显而易见的。特别注意对所有非典型表示和一些不可分解表示的分析。
All finite‐dimensional irreducible representations of the general linear Lie superalgebra gl(2/2) are written down in matrix form. The basis within each representation space is chosen in such a way that it makes evident the decomposition of gl(2/2) into irreducible representations of its even subalgebra gl(2)⊕gl(2). Special attention is devoted to the analysis of all nontypical representations and some indecomposible representations.
