Corrections to Quantum cohomology and closed-string mirror symmetry for toric varieties
Corrections to Quantum cohomology and closed-string mirror symmetry for toric varieties
In Corollary 1.3/Corollary 2 (depending on whether you look in the published version or in the arXiv or accepted version) the map should be a Λ _0-algebra homomorphism, not just a Λ _0-module homomorphism. This ensures that the situation reduces to the classical Stanley-Reisner presentation modulo Λ _+.
In Corollaries 4.17 and 4.18/Corollaries 4.16 and 4.17 (published version/arXiv or accepted version) the rings Λ _0 and R[T] should be Λ and R[T^{\pm 1}] respectively. It's explained in the surrounding text that you need to invert the Novikov variable T to make the toric divisors invertible, but this was missed from the statements of the Corollaries.
