On the proof theory of infinitary modal logic

WebAn infinitary proof theory is developed for modal logics whose models are coalgebras of polynomial functors on the category of sets. The canonical model method from modal logic is adapted to construct a final coalgebra for any polynomial functor. The ... WebHow can we define infinitary proofs? In the first order logic the usual notion of a formal proof for a sentence σ from a theory T is a "finite" sequence ( < ω - sequeance) of sentences which each one of them is a valid sentence or an axiom of T or is produced by deduction rules from former sentences. Also this sequence "ends" by σ.
