Temporal logic and its application to normative reasoning
Emiliano Lorini · Journal of Applied Non-Classical Logics · 2013
I present a variant of with time, called (Temporal ), interpreted in standard Kripke semantics. On the syntactic level, is nothing but the extension of atemporal individual by: (i) the future tense and past tense operators, and (ii) the operator of group agency for the grand coalition (the coalition of all agents). A sound and complete axiomatisation for is given. Moreover, it is shown that supports reasoning about interesting normative concepts such as the concepts of achievement obligation and commitment.
