Definition

A Poisson manifold is a differential manifold equipped with an additional structure called Poisson structure described below:

A Poisson structure is a $\mathbb {R}$-bilinear map $\{,\}:C^{\infty }(M)\times C^{\infty }(M)\to C^{\infty }(M)$, turning $C^{\infty }(M)$ into a Poisson algebra. More explicitly, the following identities are satisfied:

• $\{f,g\}=-\{g,f\}$
• $\{f,\{g,h\}\}+\{g,\{h,f\}\}+\{h,\{f.g\}\}=0$
• $\{fg,h\}=f\{g,h\}+g\{f,h\}$
