Abstract
In this article we shall give a survey of Hasse’s problem for integral power bases of algebraic number fields during the last half of century. Specifically, we developed this problem for the abelian number fields and we shall show several substantial examples for our main theorem [7] [9], which will indicate the actual method to generalize for the forthcoming theme on Hasse’s problem [15].
Highlights
In 1960’s Hasse proposed to characterize number fields whose rings of integers have power integral bases
We denote the discriminant of a number α and of a field F by dF (α) and dF, respectively
If the ring ZL2 has an integral power basis, which is generated by ξ, the equation (3.4) should hold
