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 non-commutative Valdivia compact spaces that are not Valdivia.
Characterization of (semi-)Eberlein compacta using retractional skeletons
Quasiorders for a characterization of iso-dense spaces
