Free field representations for the affine superalgebra sl(2|1)

الأصل · EN

Free field representations of the affine superalgebra A(1,0)⁽¹⁾ at level k are needed in the description of the noncritical N=2 string. The superalgebra admits two inequivalent choices of simple roots. We give the Wakimoto representations corresponding to each of these and derive the relation between the two at the quantum level.
