Abstract
For pseudoconvex domains in \(\mathbb{C}^{n}\) we prove a sharp lower bound for the Bergman kernel in terms of volume of sublevel sets of the pluricomplex Green function. For n = 1 it gives in particular another proof of the Suita conjecture. If \(\Omega \) is convex then by Lempert’s theory the estimate takes the form \(K_{\Omega }(z) \geq 1/\lambda _{2n}(I_{\Omega }(z))\), where \(I_{\Omega }(z)\) is the Kobayashi indicatrix at z. One can use this to simplify Nazarov’s proof of the Bourgain-Milman inequality from convex analysis. Possible further applications of Lempert’s theory in this area are also discussed.
