Abstract

In spite of the fact that several ab-initio schemes for the treatment of local defects in otherwise perfect crystals are becoming operational,1–6 this area of research is still, in a sense, in its infancy. Providing a proper physical description of the problem, formulating suitable approximations, implementing powerful algorithms, interpreting correctly the results of the calculations are challenges to workers active in the field. The present contribution considers some general aspects of this problem, and is divided in two parts.
