Collected Papers I

From the reviews: "The broad lines of Kummer's
number-theoretic ideas now form an essential part of our heritage: it is
fascinating to follow the details of their evolution... Volume I consists of Kummer's
number theory. It constitutes a unity of thought and spirit almost from first
sentence to last. One of the joys of reading it is in the double spectacle: the
steady train of mathematical content, unimpeded by lack of basic algebraic
number theory; while here and there, to serve problems at hand, the deft,
unobtrusive forging of pieces of present day technique. It is not hard to get
into, even for those of us who have had little contact with the history of our
subject. Cleft though one may think one is from historical sources, on reading
Kummer one finds that the rift is jumpable, the jump pleasurable. The reader
is greatly helped in this jump in two ways. Firstly, included in the volume is a
continuum of well-written, moving letters from Kummer to Kronecker giving
the details of many of Kummer's important discoveries as they freshly
occurred to him (these, together with some letters from Kummer to his mother, form part of a description of Kummer's work by Hensel on the
occasion of the centenary of Kummer's birth, also included in the volume).
Secondly, there is an excellent introduction, in which Weil describes the main
lines of Kummer's work, and explains its relations to Kummer's contemporaries,
and to us."
