利用Wakimoto自由域的思想,构造了李超代数D(2,1; α)在多项式代数和含单参数λ的外代数的张量积上的一类表示.然后得到了表示不可约的充要条件。事实上,表示是不可约的当且仅当参数λ满足对任意m ∈ λ +。
By using the idea of Wakimoto’s free field, we construct a class of representations for the Lie superalgebraD(2, 1; α) on the tensor product of a polynomial algebra and an exterior algebra involving one parameter λ. Then we obtain the necessary and sufficient condition for the representations to be irreducible. In fact, the representation is irreducible if and only if the parameter λ satisfiesfor anym∈ ℤ+.
