On Open Mappings of Compactifications of the Ray onto an Arc
The existence of an open mapping from a compactification of a ray onto the closed unit interval [0, 1] is investigated. The main theorem says that such an open mapping does exist if only if there is a confluent mapping of the remainder onto [0, 1].
