  Vafa's semi-Ricci flat metric

+ 3 like - 0 dislike
857 views

Cumrun Vafa and Greene-Shapere-Yau introduced semi-Ricci flat metric here:

B. Greene, A. Shapere, C. Vafa, and S.-T. Yau. Stringy cosmic strings and noncompact Calabi-Yau manifolds. Nuclear Physics B, 337(1):1–36, 1990

I know that such metrics are Kähler in fiber direction. Is there any counterexample to show that such metrics need not be not Kähler in horizontal direction?
