Singularities of Narasimhan-Simha type metrics on direct images of relative pluricanonical bundles  [ Singularités des métriques de type Narasimhan-Simha sur l’image directe du fibré pluricanonique relatif ]
Annales de l'Institut Fourier, Tome 66 (2016) no. 2, pp. 753-783.

Nous étudions les singularités des métriques hermitiennes de Narasimhan-Simha sur les images directes des fibrés pluricanoniques relatifs. La majoration est liée aux seuils log-canoniques.

We study singularities of the Narasimhan-Simha Hermitian metric on the direct image of a relative pluricanonical bundle. The upper bound relates to log-canonical thresholds.
