Burns–Krantz conjecture for finite-type pseudoconvex domains

Let ΩCd\Omega \subset \mathbb{C}^d be a pseudoconvex domain of finite type and let ξ0Ω\xi_0 \in \partial \Omega. A holomorphic self-map is a map f:ΩΩf:\Omega\to\Omega that is holomorphic. Burns–Krantz conjecture. There exists an integer mm, depending on the geometry of Ω\partial\Omega at ξ0\xi_0, such that if

f(z)=z+o(zξ0m),f(z)=z+o\left(\left\|z-\xi_0\right\|^m\right),

then f=idf=\operatorname{id}. This asks whether finite type supplies a boundary Schwarz lemma for weakly pseudoconvex domains, extending the known strongly pseudoconvex result; the optimal dependence of mm on the boundary geometry is not specified.
