In mesoscopic physics study of electronic transport is one of the prominent areas. During past two decades a vast amount of research has been made on the ballistic,duffusive and tunnelling transport. In this area experiment is well ahead of the theory. The only theory in common use is the "Landauer-Büttiker formalism", which has demonstrated considerable success. In the current proposal we intend to examine a general microscopic linear response approach to deal with the electronic transport in a variety of physical situations with and without a magnetic field. A careful analysis is necessary to compare linear response and Landauer-Büttiker theories.
