Brezis-Browder Principle Revisited


Most of the known (sequential) maximality principles are logical equivalents of the Brezis-Browder’s [Adv. Math., 21 (1976), 355-364]. But, for at least one of these, the inclusional relation cannot be reversed. It is our aim to put this (metrical) statement in its natural (abstract) framework. Some applications of these facts to Zorn maximality principles are then given.
