Abstract: | It is proved that -completeness is equivalent to -completeness (defined by Saxon and Sánchez Ruiz), and becomes a new characteristic condition for local completeness. The relationship between dual local completeness, dual local quasi-completeness and the Banach-Mackey property is investigated. For a quasi-Mackey space, dual local quasi-completeness, -quasi-barrelledness, Ruess' property (quasi-L) and -quasi-barrelledness are equivalent to each other. |
