We study the representation theory of the superconformal algebra Wk(g,fθ) associated with a minimal gradation of g. Here, g is a simple finite-dimensional Lie superalgebra with a non-degenerate, even supersymmetric invariant bilinear form. Thus, Wk(g,fθ) can be one of the well-known superconformal algebras including the Virasoro algebra, the Bershadsky-Polyakov algebra, the Neveu-Schwarz algebra, the Bershadsky-Knizhnik algebras, the N=2 superconformal algebra, the N=4 superconformal algebra, the N=3 superconformal algebra and the big N=4 superconformal algebra. We prove the conjecture of V. G. Kac, S.-S. Roan and M. Wakimoto for Wk(g,fθ). In fact, we show that any irreducible highest weight character of Wk(g,fθ) at any level k∈ C is determined by the corresponding irreducible highest weight character of the Kac-Moody affinization of g.
