Peak sections and Bergman kernels on Kähler manifolds with complex hyperbolic cusps

By revisiting Tian's peak section method, we obtain a localization principle of the Bergman kernels on Kahler manifolds with complex hyperbolic cusps, which is a generalization of Auvray-Ma-Marinescu's (Math Ann 379:51-1002, 2021) localization result Bergman kernels on punctured Riemann surfaces . Then we give some further estimates when the metric on the complex hyperbolic cusp is a Kahler-Einstein metric or when the manifold is a quotient of the complex ball. By applying our method directly to Poincare type cusps, we also get a partial localization result.
