A noncommutative gauge theory is associated to every Abelian gauge theory o
n a Poisson manifold. The semi-classical and full quantum version of the ma
p from the ordinary gauge theory to the noncommutative gauge theory (Seiber
g-Witten map) is given explicitly to all orders for any Poisson manifold in
the Abelian case. In the quantum case the construction is based on Kontsev
ich's formality theorem, (C) 2000 Elsevier Science B.V. All rights reserved
