Resumen de On a Characterization of W-Sets

Jonathan Hatch

• A proper subcontinuum H of a continuum X is said to be a W-set provided for each continuous surjective function f from a continuum Y onto X, there exists a subcontinuum C of Y that maps entirely onto H. Descriptions, definitions, and results concerning two new types of W-sets are given, as well as a new characterization of W-sets.
