Growing specialization and diversification have brought a host of mono-
graphs and textbooks on increasingly topics. However, the "tree" of
knowledge of mathematics and related fields does not grow only by
putting forth new branches. It also happens, quite often in fact, that
branches which were thought to be completely disparate are suddenly seen
to be related. Further, the kind and level of sophistication of
mathematics applied in various sciences has changed drastically in
recent years: measure theory is used (non-trivially) in regional and
theoretical economics; algebraic geometry interacts with physics; the
Minkowsky lemma, coding theory and the structure of water meet one
another in packing and covering theory; quantum fields, crystal defects
and mathematical pro- gramming profit from homotopy theory; Lie algebras
are relevant to filtering; and prediction and electric engineering can
use Stein spaces. And in addition to this there are such new emerging
subdisciplines as "complete integrable systems", "chaos, synergetics and
large-scale order", which are almost impossible to fit into the existing
classifica- tion schemes. The draw upon widely different sections of
mathematics.
