The geometrical description of deformation quantization based on quant
um duality principle makes it possible to introduce deformed Lie-Poiss
on structure. It serves as a natural analogue of classical Lie bialgeb
ra for the case when the initial object is a quantized group. The expl
icit realization of the deformed Lie-Poisson structure is a difficult
problem. We study the special case of such constructions characterized
by quite a simple form of tangent vector fields. In this case 4 Lie c
ompositions define 2 deformations of the first order and 4 Lie bialgeb
ras and give rise to 2 families of deformed Lie-Poisson structures. Th
e explicit example is studied.
