The main aim of this paper is to define the localization of a tetravalent modal algebra [Formula: see text] with respect to a topology [Formula: see text] on [Formula: see text]. In Sec. 5, we prove that the tetravalent modal algebra of fractions relative to a ∧-closed system (defined in Definition 3.1) is a tetravalent modal algebra of localization.
