On multiplicity and boundary behavior of quasiregular mappings
Abstract.
We study the boundary behavior of a bounded quasiregular mapping in $n$-dimensional Euclidean space $\mathbb{R}^n$. Lindel\"of-type problems are studied in connection with the local topological index $i(x,f)$. Conditions for the existence of certain types of limits at a given boundary point $b$ are shown. The function is assumed to have a limit along the given sequence points approaching the boundary point $b$ and the topological indices are required to grow to infinity at sufficient rate.
