On a conjecture of Tian [PDF]

open access: yesMathematische Zeitschrift, 2017
Let \(X\) be a complex projective manifold, and let \(L\) be an ample line bundle on \(X\). Tian's \(\alpha\)-invariant \[ \alpha(X, L) = \text{sup} \{ \lambda \in \mathbb Q \;| \;(X, \lambda D) \;\text{is log-canonical for every} \;D \geq 0, \;D \sim_{\mathbb Q} L \} \] plays an important role for the existence of special metrics on \(X\), but is very
