Notation Table

Polish- or Łukasiewicz's notation for logic

• The table below shows the core of w:Jan Łukasiewicz's notation for w:sentential logic, or Propositional Logic. The "conventional" notation did not become so until the 1970s and 80s. Some letters in the Polish notation table means a certain word in Polish, as shown:

Concept	Conventional notation	Polish notation	Polish / English word
w:Negation	${\displaystyle \neg \phi }$	Nφ	negation (No)}
Conjunction	${\displaystyle \phi \land \psi }$	Kφψ	conjunction
w:Disjunction	${\displaystyle \phi \lor \psi }$	Aφψ	alternate OR=disjunction
w:Material conditional	${\displaystyle \phi \to \psi }$	Cφψ	implication
w:Biconditional	${\displaystyle \phi \leftrightarrow \psi }$	Eφψ	equivalence'
w:Falsum	${\displaystyle \bot }$	O	False value
w:Sheffer stroke	${\displaystyle \phi \mid \psi }$	Dφψ	Sheffer stroke
Possibility	${\displaystyle \Diamond \phi }$	Mφ	contingent
Necessity	${\displaystyle \Box \phi }$	Lφ	Necessary condition
w:Universal quantifier	Πpφ	kwantyfikator ogólny	ANY: For all p, \phi|Universal quantifier
Existential quantifier	${\displaystyle \exists p\,\phi }$	Σpφ	Exists

• Note that the quantifiers ranged over propositional values in Łukasiewicz's work on many-valued logics.
