15 Consider a super Calabi-Yau hypersurface M = {G = 0} WCP (6 ) (,,,,,,3 q, q )[6], G = φ 6 + φ6 + φ6 3 + φ3 4 + φ3 5 + φ3 6 + φ 7 + ξ ξ. Via Sethi s proposed correspondence, for appropriately chosen (q, q ), M is associated with the Landau-Ginzburg orbifold where G bos /J bos, G bos = φ 6 + φ6 + φ6 3 + φ3 4 + φ3 5 + φ3 6 + φ 7 J bos : φ i e πiq i /s φ i. Using the techniques of Vafa (989) and Intriligator & Vafa (990), the Hodge diamond of G bos /J bos is determined to be The Hodge diamond of M should agree with this result. 5
16 Using Sethi s heuristic method for computing supermanifold Hodge numbers, one obtains for (q, q ) {(,5),(3,3)} untwisted sector z } { third twisted sector z } { For (q, q ) = (,4), the only contribution to the Hodge diamond arises from the untwisted sector and we obtain Thus, for all possible choices of (q, q ), Sethi s heuristic method does not yield agreement with the Landau-Ginzburg orbifold Hodge diamond. 6
