摘要

Paired series of strongly subspectral molecular graphs which possess a preponderance of common eigenvalues can be constructed by successive attachment of specific aufbau units (repeated subgraphs) to certain seed graphs. Recursion relations for the characteristic polynomials of such series are identical and differ only in the input of initial characteristic polynomials. A new operator method for the derivation of recursion relations for singly connected polymeric series is presented. Strongly subspectral series devolve to the same infinite-limit member and density of states, and two types of end-group effects are demonstrated.
