Abstract

Let Ω\Omega be a domain in Cn\mathbb C^n. Suppose that Ω\partial\Omega is smooth pseudoconvex of D'Angelo finite type near a boundary point ξ0Ω\xi_0\in \partial\Omega and the Levi form has corank at most 11 at ξ0\xi_0. Our goal is to show that if the squeezing function sΩ(ηj)s_\Omega(\eta_j) tends to 11 or the Fridman invariant hΩ(ηj)h_\Omega(\eta_j) tends to 00 for some sequence {ηj}Ω\{\eta_j\}\subset \Omega converging to ξ0\xi_0, then this point must be strongly pseudoconvex.
