It is a classical problem in algebraic number theory to decide if a number field is monogeneous, that is if it admits power integral bases. It is especially interesting to consider this question in an infinite parametric familiy of number fields. In this paper we consider the infinite parametric family of simplest quartic fields K generated by a root ξ of the polynomial Pt(x) = x4 − tx3 − 6x2 +tx+1, assuming that t > 0, t ≠ 3 and t2 +16 has no odd square factors. In addition to generators of… 
Monogenity in totally real extensions of imaginary quadratic fields with an application to simplest quartic fields
We describe an efficient algorithm to calculate generators of power integral bases in composites of totally real fields with imaginary quadratic fields. We show that the calculation can be reduced to
Minimal indices of pure cubic fields
The minimal index of a pure cubic field was shown to assume arbitrarily large values by M. Hall. In this paper we extend this result by showing that every cubefree integer occurs as the minimal index
Even Unimodular Lattices from Quaternion Algebras
We review a lattice construction arising from quaternion algebras over number fields and use it to obtain some known extremal and densest lattices in dimensions 8 and 16. The benefit of using

This paper explicitly gives all generators of power integral bases in the ring of integers ℤ K of Kt assuming that t 2+16 is not divisible by an odd square.
The simplest quartic field was first introduced by A. J. Lazarus. In this paper, we will evaluate zeta function of the simplest quartic field at s = −1. We first develop arithmetic of the simplest
