I. Holopainen et S. Rickman, FAILURE OF THE DENJOY THEOREM FOR QUASI-REGULAR MAPS IN DIMENSION N-GREATER-THAN-OR-EQUAL-TO-3, Proceedings of the American Mathematical Society, 124(6), 1996, pp. 1783-1788
In 1929 L. V. Ahlfors proved the Denjoy conjecture which states that t
he order of an entire holomorphic function of the plane must be at lea
st k if the map has at least 2k finite asymptotic values. In this pape
r, we prove that the Denjoy theorem has no counterpart in the classica
l form for quasiregular maps in dimensions n greater than or equal to
3. We construct a quasiregular map of R(n), n greater than or equal to
3, with a bounded order but with infinitely many asymptotic limits. O
ur method also gives a new construction for a counterexample of Lindel
of's theorem for quasiregular maps of B-n, n greater than or equal to
3.
