The Product of Poisson Manifolds
Given two Poisson manifolds (M,{⋅,⋅}M) and (N,{⋅,⋅}N), a Poisson bracket may be defined on the product manifold M × N. Letting f1 and f2 be two smooth functions defined on M × N, one can define a new Poisson bracket {⋅,⋅}M × N in terms of {⋅,⋅}M and {⋅,⋅}N as follows:
- ,
where x ∈ M and y ∈ N are to be held constant. In other words, if
- ,
then both
and
are implied.

Famous quotes containing the word product:
“The guys who fear becoming fathers dont understand that fathering is not something perfect men do, but something that perfects the man. The end product of child raising is not the child but the parent.”
—Frank Pittman (20th century)
