Complexity of Cut-Elimination

Part of the Trends in Logic book series (TREN, volume 34)


Our aim is to compare different methods of cut-elimination. For this aim we need logic-free axioms. The original formulation of LK by Gentzen also served the purpose of simulating Hilbert-type calculi and deriving axiom schemata within fixed proof length. Below we show that there exists a polynomial transformation from an LK-proof with arbitrary axioms of type AA to atomic ones.
