Axiomatisation del logica propositional
Un del aspectos plus cognoscite del travalio de Łukasiewicz es su axiomatisationes del logica propositional. Un de iste axiomatisationes consiste a pena in tres axiomas que, in notation moderne, pote esser scribite del sequente forma:
A partir de iste tres axiomas, le formulas valide del logica propositional pote esser inferite via substitution e/o modus ponens. Łukasiewicz etiam presentava un revision de un systema axiomatic de Nicod que usa a pena un connective e possede a pena un axioma.
Altere grande attingimento de Łukasiewicz esseva un notation pro logica propositional non ambigue, sufficiente pro permitter a elimination de parenthesis e altere signos usate pro determinar le objetivo del connectives logic. Iste notation es cognoscite como notation polonese e in illo le connectivos logic es prefixate in vice de infixate como accide in le notation usual. Iste notation ha importantia theoric pro le scientias del computation.
