Abstract
A new formalism to investigate RKKY interaction in aperiodic materials is presented. Particularly useful in the tight-binding scheme, it is used in this paper to probe the role of local environment and long range quasiperiodic potential on this mesoscopic coupling. Interesting features are revealed and discussed within the context of anomalous localization and transport
