The developments we have been describing thus far lasted close to a century.They
gave rise to important “concrete” theories—Galois theory,algebraic number theory,
algebraic geometry—in which the (at times implicit) field concept played a central
role.
At the end of the nineteenth century abstraction and axiomatics were “in the air.”
For example,Pasch (1882) gave axioms for projective geometry,stressing for the
first time the importance of undefined notions,Cantor (1883) defined the real numbers as equivalence classes of Cauchy sequences of rationals,and Peano (1889) gave his axioms for the natural numbers.In algebra,von Dyck (1882) gave an abstract
definition of a group which encompassed both finite and infinite groups (about thirty
years earlier Cayley had defined a finite group),and Peano (1888) gave a definition
of a finite-dimensional vector space,though this was largely ignored by his contemporaries.The time was propitious for the abstract field concept to emerge.Emerge it did in 1893 in the hands ofWeber (of Dedekind–Weber fame).
Weber’s definition of a field appeared in his 1893 paper “General foundations of
Galois’ theory of equations” [23],in which he aimed to give an abstract formulation
of Galois theory:
In the following an attempt is made to present the Galois theory of algebraic equations in a way which will include equally well all cases in which this theory might be used.Thuswepresent it here as a direct consequence of the group concept illuminated by the field concept,as a formal structure completely without reference to any numerical interpretation of the elements used.
Weber’s presentation of Galois theory is indeed very close to the way the subject
is taught today.His definition of a field,preceded by that of a group,is as follows:
A group becomes a field if two types of composition are possible in it,the
first of which may be called addition,the second multiplication.The general
determination must be somewhat restricted,however.
1.We assume that both types of composition are commutative.
2.Addition shall generally satisfy the conditions which define a group.
Although the associative law under multiplication is missing,and the axioms are
not independent,they are of course very much in the modern spirit.As examples
of his newly-defined concept Weber included the number fields and function fields
of algebraic number theory and algebraic geometry,respectively,but also Galois’
finite fields and Kronecker’s “congruence fields” K[x]/(p(x)),K a field,p(x) a
polynomial irreducible over K.
Weber proved (often reproved,after Dedekind) various theorems about fields
which later became useful in Artin’s formulation of Galois theory,and which are
today recognized as basic results of the theory.
后面这个翻译不翻译都可以的。如果 磨练下自己,那我太感激了。
In an 1899 article entitled “New foundations of the theory of algebraic numbers,”
Hensel began a life-long study of p-adic numbers.Inspired by the work of Dedekind–
Weber we have described above,Hensel took as his point of departure the analogy
between function fields and number fields (p.55).Just as power series are useful for
a study of the former,Hensel introduced p-adic numbers to aid in the study of the
latter:
The analogy between the results of the theory of algebraic functions of one
variable and those of the theory of algebraic numbers suggested to me many
years ago the idea of replacing the decomposition of algebraic numbers,with
the help of ideal prime factors,by a more convenient procedure that fully
corresponds to the expansion of an algebraic function in power series in the
neighborhood of an arbitrary point.
