quantifier by Raven58 on 2005-08-20 11:37:15
RE: Existential Quantifier definition

Using '(x)' for the universal quantifier and 'Ex' for existential quantifer, the definition of 'existential quantifier' as the dual of the universal should read:

Exg(x) = ~(x)~g(x)

That is, for the dual of the universal, replace the existential with the universal.

Thanks, Ken
