“…This approach has been successfully explored mainly when the underlying variety X admits Kähler metrics of non-positive sectional curvature. For example, if (X, ω B ) is a n-dimensional complex hyperbolic manifold equipped with the standard locally symmetric metric Bergman metric whose holomorphic sectional curvature is normalized to be −1, J.-M. Hwang and W.-K. To in [HT99] were able to prove that (K X ; x) ≥ (n + 1) sinh 2 (i x /2) where i x is the injectivity radius of ω B at x. Similarly, if (X, ω) is a n-dimensional compact Kähler manifold with non-positive sectional curvature, say −a 2 ≤ R ω ≤ 0, and L is an ample line bundle on X, then S.-K. Yeung in [Yeu00] shows that (L; x) ≥ δ(i x , a, L; n) where δ is an explicitly computable function of the injectivity radius i x , the curvature bounds, the curvature of L and the dimension.…”
