In 1982 Siu and Yang proved that under certain pinching of the holomorphic sectional curvature, a compact Kaehler Einstein surface with negative bisectional holomorphic curvature has the complex ball in C^2 as the universal cover. We discuss our recent work proving a conjecture (jointly proposed in 1988  with  Y. Hong and H. Yang) on the pinching constant.
