RésumeA complex hyperbolic cusp is an end of a finite-volume quotient of complex hyperbolic space. Up to a finite cover, any such cusp can be realized as the punctured unit disk bundle of a negative line bundle over an abelian variety. The Dirichlet problem for complete Kähler-Einstein metrics on this space with boundary data prescribed on the unit circle bundle is well-posed. We determine the precise asymptotics of its solutions towards the zero section. I will also explain an application to the geometry of degenerating Kähler-Einstein metrics on surfaces of general type via gluing. This is joint work with Xin Fu and Xumin Jiang.
