Abstract: A decimation method for electron systems is described. In this method we study the properties of a Hamiltonian under the real-space renormalisation-group transformation, in which the system at each step is regarded as an assembly of the sites with a larger lattice spacing interacting via renormalised site energies and transfer energies. The method is applied to the Anderson-transition problem for random systems and the numerical results for different dimensionalities are presented.
