Abstract
The average Green function and the self-energy of a many-component disordered alloy is determined in a quasi-crystalline approximation. Second-order correlations between different lattice sites are taken into account. The summation method of Lloyd for the calculation of the density of states for a liquid is modified to make it applicable for an alloy. Finally the coherent-potential approximation is discussed for the considered general alloy model.
