Cyclotomic character — In number theory, a cyclotomic character is a character of a Galois group giving the Galois action on a group of roots of unity. As a one dimensional representation over a ring R, its representation space is generally denoted by R(1) (that is, it … Wikipedia
Galois module — In mathematics, a Galois module is a G module where G is the Galois group of some extension of fields. The term Galois representation is frequently used when the G module is a vector space over a field or a free module over a ring, but can also… … Wikipedia
Herbrand–Ribet theorem — In mathematics, the Herbrand–Ribet theorem is a result on the class number of certain number fields. It is a strengthening of Kummer s theorem to the effect that the prime p divides the class number of the cyclotomic field of p th roots of unity… … Wikipedia
Artin reciprocity law — The Artin reciprocity law, established by Emil Artin in a series of papers (1924; 1927; 1930), is a general theorem in number theory that forms a central part of the global class field theory.[1] The term reciprocity law refers to a long line of… … Wikipedia
Artin L-function — In mathematics, an Artin L function is a type of Dirichlet series associated to a linear representation ρ of a Galois group G . These functions were introduced in the 1923 by Emil Artin, in connection with his research into class field theory.… … Wikipedia
