Theorem

The set of logical connectives:

$\set {\neg, \land, \lor}$: Not, And and Or

is functionally complete.


Proof

From the stronger results:

Functionally Complete Logical Connectives: Negation and Disjunction:
the set of logical connectives: $\set {\neg, \lor}$ is functionally complete
Functionally Complete Logical Connectives: Negation and Conjunction:
the set of logical connectives: $\set {\neg, \land}$ is functionally complete

it follows directly that $\set {\neg, \land, \lor}$ is likewise functionally complete.

$\blacksquare$
