Asymptotic characterizations of strong pseudoconvexity on pseudoconvex domains of finite type in ℂ^2

In this paper, we provide some characterizations of strong pseudoconvexity by the boundary behavior of intrinsic invariants for smoothly bounded pseudoconvex domains of finite type in ℂ^2. As a consequence, if such domain is biholomorphically equivalent to a quotient of the unit ball, then it is strongly pseudoconvex.
