The first volume of the series, on "The Stability of the Differentiated
State" received many favorable reviews from the scientific community.
Many readers seem to agree with us that publication of topical volumes
is a worthwhile alternative to periodic compilations of rather
unrelated, though up-to-date reviews. Production of topical volumes is
however, plagued with one great difficulty, that of "author
synchronization". This difficulty explains the lag between volumes 1 and
2 of the series. Nevertheless we hope that the present volume will be
appreciated as a valuable source of information on its central topic:
