Abstract
From a commutative associative algebra with a basis
the infinite dimensional unital Nambu–Poisson algebra of order 3 is constructed, which is also a canonical Nambu–Poisson algebra, and its structures and derivations are discussed. It is proved that: (1) there is a minimal set of generators of
consisting of six vectors; (2) the quotient 3-Lie algebra
is simple; (3) four infinite dimensional 3-Lie algebras: the 3-Virasoro–Witt algebra
(
),
and the
3-algebra can be embedded in the unital Nambu–Poisson algebra of order 3.
