Connections between classes of spaces and of mappings
Janusz J. Charatonik and Wlodzimierz J. Charatonik
R. W. Wardle has used a function with hyperspace values to prove some
connections between the property of Kelley and confluent mappings.
We generalize this idea to define classes of objects and of morphisms in a
category, and to investigate some relations between these classes.
The obtained results are applied to continuum
theory.
