Geometry of Reinhardt domains of finite type in ℂ2

Abstract

The asymptotic behavior of the holomorphic sectional curvature of the Bergman metric on a pseudoconvex Reinhardt domain of finite type in ℂ2 is obtained by rescaling locally the domain to a model domain that is either a Thullen domain Ω m = {(z 1,z 2); ¦z 1¦2 + ¦z 2¦2m < 1 or a tube domainT m = {(z 1,z 2); Imz1 + (Imz2)2m < 1}. The Bergman metric for the tube domainT m is explicitly calculated by using Fourier-Laplace transformation. It turns out that the holomorphic sectional curvature of the Bergman metric on the tube domainT m at (0, 0) is bounded above by a negative constant. These results are used to construct a complete Kahler metric with holomorphic sectional curvature bounded above by a negative constant for a pseudoconvex Reinhardt domain of finite type in ℂ2.
