Kähler-Einstein metrics on Fano manifolds. II: Limits with cone angle less than 2𝜋

This is the second of a series of three papers which prove the fact that a K -stable Fano manifold admits a Kähler-Einstein metric. In this paper we consider the Gromov-Hausdorff limits of metrics with cone singularities in the case when the limiting cone angle is less than 2 π {π } . We show that these are in a natrual way projective algebraic varieties. In the case when the limiting variety and the limiting divisor are smooth we show that the limiting metric also has standard cone singularities.
