[Noyaux de Bergman pour une suite de métriques de solitons de Kähler–Ricci tordus]
Dans ce papier, nous montrons une conjecture due à Tian concernant une estimation partielle pour une suite de métriques de Kähler–Einstein tordues sur les variétés de Fano, ou plus généralement, pour une suite des solitons de Kähler–Ricci tordus. Ceci généralise les résultats de Donaldson–Sun–Tian pour une suite de métriques de Kähler–Einstein sur les variétés de Fano. Comme application, nous démontrons que la limite de Gromov–Hausdorff de la suite est homéomorphe à une variété de -Fano à singularités log terminales qui admet un soliton de Kähler–Ricci sur sa partie régulière.
In this paper, we prove the partial -estimate conjecture of Tian for an almost Kähler–Einstein metrics sequence of Fano manifolds, or more general, an almost Kähler–Ricci solitons sequence. This generalizes Donaldson–Sun–Tian’s result for a Kähler–Einstein metrics sequence of Fano manifolds. As an application, we prove that the Gromov–Hausdorff limit of sequence is homeomorphic to a log terminal -Fano variety which admits a Kähler–Ricci soliton on its smooth part.
