In science:

The structure of the paper is as follows: Section 2 contains basic notions from topology, topological model theory, and the topological semantics for modal logic.
Modal languages for topology: expressivity and definability
In Section 5, we consider a number of extensions of the basic modal language and characterize definability in these richer languages.
Modal languages for topology: expressivity and definability
In this section we recall some basic notions from topology, topological model theory, and the topological semantics for modal logic.
Modal languages for topology: expressivity and definability
We recall syntax and the topological semantics for the basic modal language.
Modal languages for topology: expressivity and definability
In this paper, however, we study the topological semantics, according to which modal formulas denote regions in a topological space.
Modal languages for topology: expressivity and definability
Definition 5 (Topological semantics of the basic modal language).
Modal languages for topology: expressivity and definability
Each modal formula φ defines a set of points in a topological model (namely the set of points at which it is true).
Modal languages for topology: expressivity and definability
We extend the notions of truth and validity to the sets of modal formulas in the usual way (e.g., X |= Γ means that X |= φ for each φ ∈ Γ).
Modal languages for topology: expressivity and definability
Given a class K of spaces, the set of modal formulas {φ ∈ ML | K |= φ} (“the modal logic of K”) is denoted by Log(K).
Modal languages for topology: expressivity and definability
Conversely, given a set of modal formulas Γ, the class of spaces {X | X |= Γ} is denoted by Sp(Γ).
Modal languages for topology: expressivity and definability
Thus, in this notation, a class K is modally definable iff Sp(Log(K)) = K.
Modal languages for topology: expressivity and definability
The following example illustrates the concept of modal definability.
Modal languages for topology: expressivity and definability
This shows that all the above results on Lt also apply to modal formulas.
Modal languages for topology: expressivity and definability
Let Σ ⊆ ML be a set of modal formulas (in a countable signature).
