 In particular, for formula_40 and non negative integers "k" there are "k + 1" primary fields formula_41 's corresponding to spin j representation ( "j = 0, 1/2, 1, 3/2.., k/2").The correlation function formula_42 of the primary fields formula_41 's for the representation formula_44 takes values in the tensor product formula_45 and its KZ equation is
where formula_47 as the above informal derivation.This "n"-point correlation function can be analytically continued as multi-valued holomorphic function to the domain formula_48 with formula_49 .
