| Oct 5, 2014 at 4:01 | comment | added | Igor Belegradek | I think the metric coming from the solution of Calabi conjecture need not have negative sectional curvature. The conjecture I mention in the first comment is taken from [Siu, Yum Tong; Yang, Paul Compact Kähler-Einstein surfaces of nonpositive bisectional curvature. Invent. Math. 64 (1981), no. 3, 471–487] whose authors discuss Mostow-Sie example in the introduction. | |

| Oct 5, 2014 at 3:41 | comment | added | Igor Belegradek | If memory serves, Mostow-Siu metric is not Einstein. I think there is a conjecture that any Kahler-Einstein surface of negative sectional curvature is covered by $CH^2$. | |
