Chapter 13 BOOLEAN ALGEBRA
... Notice that the two definitions above refer to "...a greatest lower bound" and "a least upper bound." Any time you define an object like these you need to have an open mind as to whether more than one such object can exist. In fact, we now can prove that there can't be two greatest lower bounds or t ...

... L-formulas. A language L is complete if and only if every Boolean function can be defined by an L-formula. Propositional logic can be formulated with any complete (usually finite) language L — for the time being, we shall use the language ¬, ∧, ∨ and ⊃. A propositional formula A is said to be a taut ...

... Sentences P and Q of PLE are quantificationally equivalent if there is no interpretation on which P and Q have different truth values. A set Γ of sentences of PLE is quantificationally consistent if there is an interpretation on which every member of Γ is true. A set Γ of sentences of PLE quantific ...
