Аннотация:In the last few years the use of geometric methods has permeated many more
branches of mathematics and the sciences. Briefly its role may be characterized
as follows. Whereas methods of mathematical analysis describe phenomena ‘in
the small’, geometric methods contribute to giving the picture ‘in the large’.
A second no less important property of geometric methods is the convenience
of using its language to describe and give qualitative explanations for diverse
mathematical phenomena and patterns. From this point of view, the theory of
vector bundles together with mathematical analysis on manifolds (global anal-
ysis and differential geometry) has provided a major stimulus. Its language
turned out to be extremely fruitful: connections on principal vector bundles
(in terms of which various field theories are described), transformation groups
including the various symmetry groups that arise in connection with physical
problems, in asymptotic methods of partial differential equations with small
parameter, in elliptic operator theory, in mathematical methods of classical
mechanics and in mathematical methods in economics. There are other cur-
rently less significant applications in other fields. Over a similar period, uni-
versity education has changed considerably with the appearance of new courses
on differential geometry and topology. New textbooks have been published but
‘geometry and topology’ has not, in our opinion, been well covered from a prac-
tical applications point of view. Existing monographs on vector bundles have
been mainly of a purely theoretical nature, devoted to the internal geometric
and topological problems of the subject. Students from related disciplines have
found the texts difficult to use. It therefore seems expedient to have a simpler
book containing numerous illustrations and applications to various problems in
mathematics and the sciences.
