Title: Pointwise estimates of weighted Bergman kernels in several complex variables

Abstract: We prove new pointwise bounds for weighted Bergman kernels in ℂn, whenever a certain Laplacian acting on (0,1)-forms is coercive. Our results extend the ones obtained in ℂ by Christ.
Our main idea is to develop a version of Agmon theory (originally introduced to deal with Schrödinger operators) for these Laplacians, inspired by the fact that these may be thought as a generalization of Schrödinger operators.
