In particular those quantities which appear in the classical theorem and depend only on the component of the mapping in the complex normal direction have K-limits (not just restricted K-limits) at the boundary.10 pagesComplex VariablesFunctional Analysis30C80 (primary), 32A40, 46E22 (secondary)An improved Julia-Caratheodory theorem for Schur-Agler mappings of the unit balltext
