Abstract
We describe a method of obtaining a conductivity formula which incorporates the relaxation functions in a quasi-two-dimensional system. A parabolic co nfinement potential is adopted. We derive the relaxation function using pro jectors. We expand the propagators via the series expansion of the diagonal projectors and obtain useful relations enabling one to calculate the relax ation functions.
