The operation $\neg$ is called complementation.

Equivalence of Definitions
That the above definitions are equivalent is shown on Equivalence of Boolean Algebra Definitions.

Also defined as
Some sources define a Boolean algebra to be what on ProofWiki is called a Boolean lattice.

Others refer to a Boolean algebra as a Boolean ring or a Huntington algebra, both of which terms already have a different definition on ProofWiki.

Also known as
Common other notations include: $0$ and $1$ for $\bot$ and $\top$, respectively, and $a'$ for $\neg a$.
