The class field theory determines all Abelian extension fields of a number field on theoretical, but it is not concrete. The author has studied the arithmetic properties of cubic cyclic extensions of number fields in [1, 2]. In this report, we determine all cubic cyclic extension fields of any number field K.展开更多

The purpose of this paper is to discuss the property of the primes splitting completely in the finite extension L of number field K. If K is a number field, we denote by O_K the integer ring of K.
