WebbGentzen-type system for the propositional modal logic S5 . Therefore various alternative Gentzen-type systems for this logic that do enjoy cut-admissibility have been proposed in the literature. Among those systems, the simplest are those that employ hypersequents. Several such systems for propositional S5 WebbThe system consists of a set of rules of inference for deriving consequences from premises. One builds a proof tree whose root is the proposition to be proved and whose leaves are the initial assumptions or axioms (for proof trees, we usually draw the root at the bottom and the leaves at the top).
