The Expressive Power of Modal Dependence Logic
... logic extends standard modal logic with team semantics by modal dependence atoms, =(p1 , . . . , pn , q). The intuitive meaning of the formula =(p1 , . . . , pn , q) is that within a team the truth value of the proposition q is functionally determined by the truth values of the propositions p1 , . . ...

A BRIEF INTRODUCTION TO MODAL LOGIC Introduction Consider
... Schema K For any wffs α and β, we will assume that (α =⇒ β) =⇒ (α =⇒ β). Our proof system will also have two rules of inference. Definition 2.7. A ‘rule of inference’ is an ordered pair (Γ, α), where Γ is a set of wffs and α is a single wff. If the propositions of Γ are theorems of the system, so ...
