On proper branched coverings and a question of Vuorinen

Abstract

We study global injectivity of proper branched coverings defined on the Euclidean nn-ball in the case when the branch set is compact. In particular we show that such mappings are homeomorphisms when n=3n=3 or when the branch set is empty. This proves the corresponding cases of a question of Vuorinen from [Vuo79].
