Preliminary scope of work
Obecný pojem výrokového důkazového systému (definován Cookem a Reckhowem) zobecňuje obvyklé výrokové počty. Některé z těchto systémů používají algebru (např. Nullstellensazt). Úkolem práce je sestrojit důkazy konkrétních tautologií v jednom z těchto systémů.
Preliminary scope of work in English
The general notion of a propositional proof system (defined by Cook and Reckhow) generalizes usual propositional calculi. Some of these systems are based on algebra (e.g. Nullstellensatz). The goal of the project is to construct proofs of particular tautologies in one of such systems.
