Abstract Τhe transport properties of d isordered one-dimensional systems is studied with the use of a new me thod, which maps the initial system anto a dynamical system which is described by a parametrically excited linear oscillator. In this rep resentation the conduetance takes a simple geometrical form . Moreove r we study the statistical properties of eigenveifors,using well known methods of Quantum Chaos.In the second part,we study quasi-one-dimens ional systems which are described by bond rendom matrices. The scal ing properties of Lyapunov exponents,and the dynamics of an inially localized wavefunction are studied in details
