New examples of non-commutative Valdivia compact spaces

Abstrakt

The aim of this note is to characterize trees, endowed with coarse wedge topology, that have a retractional skeleton. We use this characterization to provide new examples of compact spaces with retractional skeleton that are not Valdivia.
