Tables, lemmas, and focused proofs
To help validate our energies at exploring focusing proof systems, the team has looked at various applications of such proof theoretic results. Miller and Nigam in [Oops!] have shown how focusing proof systems can be exploited to provide a declarative approach to the use of tables in proof search (addressing the issue of lemma reuse instead of reproof in the case of atomic lemmas). They also showed how a table of lemmas can be used to give a new form of proof certificate.
