Generalized Kummer theory and its applications
Annales mathématiques Blaise Pascal, Tome 16 (2009) no. 1, pp. 127-138.

In this report we study the arithmetic of Rikuna’s generic polynomial for the cyclic group of order n and obtain a generalized Kummer theory. It is useful under the condition that ζk and ωk where ζ is a primitive n-th root of unity and ω=ζ+ζ -1 . In particular, this result with ζk implies the classical Kummer theory. We also present a method for calculating not only the conductor but also the Artin symbols of the cyclic extension which is defined by the Rikuna polynomial.
