We consider application of the group function theory to an arbitrary infinite system consisting of weakly overlapping structural elements which may be atoms, ions, molecules, bonds, etc. We demonstrate that the arrow diagram (AD) expansion developed previously is ill-defined for such a system result

Abstract
Quantum mechanical perturbation theory of infinite order is applied to an infinitely long biological polymeric chain. The resulting ensembleβaveraged density of electronic states is approximately calculated by truncation according to a method introduced by S. Y. Wu [(1974) J. Math. Phys. 15, 947β949]. The results are found to require reasonable computational facilities and the method may be applied to a study of mutagenicity.
