Poisson Manifold - The Product of Poisson Manifolds

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 xM and yN are to be held constant. In other words, if

,

then both

and

are implied.

Famous quotes containing the word product:

    [As teenager], the trauma of near-misses and almost- consequences usually brings us to our senses. We finally come down someplace between our parents’ safety advice, which underestimates our ability, and our own unreasonable disregard for safety, which is our childlike wish for invulnerability. Our definition of acceptable risk becomes a product of our own experience.
    Roger Gould (20th century)
