Abstract: | We give characterizations of perfect images and open and compact images of spaces that can be mapped onto metrizable spaces by a mapping with fibers having a given property . We use these characterizations to obtain conditions which imply that such images can be mapped onto a metric space by a mapping with fibers satisfying . Such a treatment includes the investigation of spaces with a weaker metric topology 2, Ch. 5]. |
