Query: On Riemann-Poisson Lie groups   A Riemann-Poisson Lie group is a Lie group endowed with a left invariant
Riemannian metric and a left invariant Poisson tensor which are compatible in
the sense introduced in C.R. Acad. Sci. Paris s\'er. {\bf I 333} (2001)
763-768. We study these Lie groups and we give a characterization of their Lie
algebras. We give also a way of building these Lie algebras and we give the
list of such Lie algebras up to dimension 5.
