Query: Scattering approach to current and noise in interacting mesoscopic
  systems   We propose an extension of the Landauer-Buttiker scattering theory to include
effects of interaction in the active region of a mesoscopic conductor
structure. The current expression obtained coincides with those derived by
different methods. A new general expression for the noise is also established.
These expressions are then discussed in the case of strongly sequential
tunneling through a double-barrier resonant tunneling structure.
