Algebraic Bergman kernels and finite type domains in $\mathbb{C}^2$

Algebraic Bergman kernels and finite type domains in $\mathbb{C}^2$

Let $G \subset \mathbb{C}^2$ be a smoothly bounded pseudoconvex domain and assume that the Bergman kernel of $G$ is algebraic of degree $d$. We show that the boundary $\partial G $ is of finite type and the type $r$ satisfies $r\leq 2d$. The inequality is optimal as equality holds for …
