B. Coupet et A. Sukhov, ON THE BOUNDARY RIGIDITY PHENOMENON FOR AUTOMORPHISMS OF DOMAINS IN C-N, Proceedings of the American Mathematical Society, 124(11), 1996, pp. 3371-3380
We prove that a piecewise smoothly bounded strictly pseudoconvex domai
n with a non-compact automorphism group is biholomorphic to the ball.
A boundary version of the Schwarz lemma for automorphisms of such a do
main is settled.
