A Poisson Lie group (often written Poisson-Lie group) or Lie Poisson group is a Lie group and a Poisson manifolds, the two structures being compatible such that the group product is a smooth map of Poisson manifolds where has the product Poisson structure.
Warning: the inverse map is NOT a Poisson map unless G has the trivial Poisson structure, in fact it is an anti-Poisson map.
Deformation quantizations of Poisson Lie groups are Hopf algebras. The usual quantum groups have smaller number of quantum subgroups (i.e. Hopf quotient algebras) than the corresponding Lie group has, namely only only those whose classical limits are not only Lie subgroups but Poisson Lie subgroups.
One can regard Poisson groups as the classical limit of quantum groups: a theorem by Drinfeld established a bijection between connected, simply connected Poisson Lie groups and Lie bialgebras.
A Lie-Poisson structure is an additive Poisson Lie group (e.g. Kosmann-Schwarzbach 04, p. 46).
If is any (finite dimensional) Lie group then the dual of its tangent Lie algebra has a canonical bracket introduced by Kirillov which makes it into a Poisson Lie group. To this aim one identifies with its own tangent space and interprets the differential of a function as a function where the finite dimensionality is used. Then Kirillov defines
Given two Lie groups , the Lie algebra homomorphisms are in 1-1 correspondence with the Poisson Lie maps .
Unrelated is the concept of the Lie group that integrates the Lie algebra inside a Poisson algebra. This is instead called a quantomorphism group.
