I think the propositional calculus must have a translation into the language of Gentzen's sequent calculus. I suppose, to obtain Gentzen's version of this we should just remove from LK the rules with the quantifiers, but, perhaps, we should also remove something more, maybe the cut rule... Can anybody clarify this to me and give a reference?
