Abstract. A self‐consistent linear‐response theory for a two‐lead mesoscopic structure in Landauer's viewpoint for transport is developed. A density operator relevant in this viewpoint, in a uniform magnetic field is derived. It is shown that this operator differs from the one given in Kubo's viewpoint by a term that represents the self‐consistent effects. Hence, a special emphasis is devoted to the diagonal master equation where an exact solution is obtained in the framework of elastic scattering theory. (© 2004 WILEY‐VCH Verlag GmbH & Co.
