General class field theory used different concepts and constructions which work over every global field. The famous problems of David Hilbertstimulated further development, which led to the reciprocity laws, and proofs by Teiji Takagi, Phillip Furtwängler, Emil Artin, Helmut Hasseand many others. Visa mer In mathematics, class field theory (CFT) is the fundamental branch of algebraic number theory whose goal is to describe all the abelian Galois extensions of local and global fields using objects associated to the ground field. Visa mer Class field theory is used to prove Artin-Verdier duality. Very explicit class field theory is used in many subareas of algebraic number theory such as Iwasawa theory and Galois modules theory. Most main achievements toward the Langlands correspondence Visa mer • Non-abelian class field theory • Anabelian geometry • Frobenioid • Langlands correspondences Visa mer In modern mathematical language, class field theory (CFT) can be formulated as follows. Consider the maximal abelian extension A of a local or global field K. It is of infinite degree … Visa mer The origins of class field theory lie in the quadratic reciprocity law proved by Gauss. The generalization took place as a long-term historical … Visa mer There are three main generalizations, each of great interest. They are: the Langlands program, anabelian geometry, and higher class field theory. Often, the Langlands … Visa mer Webb4 THOMAS R. SHEMANSKE 2.2. Summary of Class Field Theory over Q. Notation: Qm = Q(e2ˇi=m).We may assume that m 6 2(4). For if m 2 (mod 4) with m = 2m0, then we easily observe that e2ˇi=m0 is a primitive mth root of unity, and hence that Q m = Qm0. Over Q, the Kronecker-Weber Theorem motiviates the following de nition:

WebbOne of the outstanding problems in arithmetic is a generalization of class field theory to non-abelian Galois extension of number fields. In this volume, we discuss some relations between this problem and cusp forms of weight 1.
