In algebraic number theory, a conductor is a modulus (in the sense of number theory) associated to an abeliannumber theory) associated to an abelian extension of number fields and reflects itsnumber fields and reflects its ramification data. It was introduced in the work of Weber at the end of 19th century. It is one of the central notions inclass field theory. A later version is due Emil Artin.
