Abstract:Orderability, weak orderability and the existence of continuous weak selections on spaces with a single non-isolated point and their products are discussed. We prove that a closed continuous image X of a suborderable space must be hereditarily paracompact provided that its product X × Y with some non-discrete space Y has a separately continuous weak selection.2010 Mathematics Subject Classification.
