Abstract:

Several refinements of Picard’s theorem for entire functions in the complex plane have been proved by many authors in connection with the theory of Picard sets. We prove a result of this type for entire quasiregular mappings in euclidean $n$-space in the case when the "Picard set" consists of a sequence ${a_k}$ on a ray emanating from 0 with $|{a_k}| = {2^k}$.
