The branching functions of a particular subclass of characters of the
affine superalgebra (sl)over-cap(2/1,C)(k) into characters of the suba
lgebra (sl)over-cap(2,C)(k) are calculated for fractional levels k = 1
/u - 1, u is an element of N. They involve rational torus A(u(u-1)) an
d Z(u-1) parafermion characters. (C) 1998 Elsevier Science B.V.
