Abstract
We show that an LK proof of size m of a monotone sequent (a sequent that contains only formulas in the basis ∧, V) can be turned into a proof containing only monotone formulas of size mO(log m) and with the number of proof lines polynomial in m. Also we show that some interesting special cases, namely the functional and the onto versions of PHP and a version of the matching principle, have polynomial size monotone proofs
