To date, the LEO-II system is, to our knowledge, the only automated higher-order theorem prover which is capable of generating joint higher-order–first-order proof objects in TPTP format. This paper discusses LEO-II’s proof objects. The target audience are practitioners with an interest in using LEO-II proofs within other systems.Keyphrases: automated theorem proving, higher order logic, proof objects In: Konstantin Korovin, Stephan Schulz and Eugenia Ternovska (editors).
