内容概要

　　group theory provides the natural mathematical language to
formulate symmetry principles and to derive their consequences in
mathematics and in physics. the "special functions" of mathematical
physics, which pervade mathematical analysis,classical physics, and
quantum mechanics, invariably originate from underlying symmetries
of the problem although the traditional presentation of such topics
may not expressly emphasize this universal feature. modern
developments in all branches of physics are putting more and more
emphasis on the role of symmetries of the underlying physical
systems. thus the use of group theory has become increasingly
important in recent years. however, the incorporation of group
theory into the undergraduate or graduate physics curriculum of
most universities has not kept up with this development. at best,
this subject is offered as a special topic course, catering to a
restricted class of students. symptomatic of this unfortunate gap
is the lack of suitable textbooks on general group-theoretical
methods in physics for all serious students of experimental and
theoretical physics at the beginning graduate and advanced
undergraduate level. this book is written to meet precisely this
need.
　　there already exist, of course, many books on group theory and
its applications in physics. foremost among these are the old
classics by weyl, wigner, and van der waerden. for applications to
atomic and molecular physics, and to crystal lattices in solid
state and chemical physics, there are many elementary textbooks
emphasizing point groups, space groups, and the rotation group.
reflecting the important role played by group theory in modern
elementary particle theory, many current books expound on the
theory of lie groups and lie algebras with emphasis suitable for
high energy theoretical physics. finally, there are several useful
general texts on group theory featuring comprehensiveness and
mathematical rigor written for the more mathematically oriented
audience. experience indicates, however, that for most students, it
is difficult to find a suitable modern introductory text which is
both general and readily understandable.
