Abstract
We investigate the relation of Souslin (antichain) properties of trees and
tree topologies. One result extends a result of Devlin and Shelah by proving, within
ZFC, the equivalence of four properties for <o,-trees-collectionwise normal, normal
and collectionwise Hausdorff, property y, and antichain normal and collectionwise
Hausdorff. A second result is the construction, assuming V = L, of an Aronszajn
tree which is not countably metacompact. Third, we show that no tree can be a
Dowker space.
