Let $K=\mathbb{Q}(\alpha)$ be a number field generated by a complex root $\alpha$ of a monic irreducible polynomial $f(x)=x^{12}-m$, with $m\neq 1$ is a square free rational integer. In this paper, we prove that if $m \equiv 2$ or $3$ (mod 4) and $m\not\equiv \mp 1$ (mod 9), then the number field $K$ is monogenic. If $m \equiv 1$ (mod 8) or $m\equiv \mp 1$ (mod 9), then the number field $K$ is not monogenic.

On certain pure sextic fields related to a problem of Hasse
TLDR
It is proved that if m is a square-free rational integer, m ≡ 1(mod 4) and m≢ ± 1( mod 9), then the pure sextic field L = Q(m6) is not monogenic.
Power integral bases for certain pure sextic fields
In this paper, we characterize whether the pure sextic fields with square-free integers m ≢ ±1(Mod 9) have power integral bases or do not; if m ≡ 2, 3 (Mod 4), then have power integral bases. We…

Power Integral Bases in Orders of Composite Fields
TLDR
It is proved that if the degree of the composite field equals the product of the degrees of its subfields and the minimal polynomials of the generating elements of the polynomial orders have a multiple linear factor in their factorization modulo q, then the composite order admits no power integral bases.
Prime ideal factorization in quartic number fields
For every prime integer p, and for every number field K defined by a p-regular polynomial, the form of the factorization of the principal ideal pℤK into prime ideals of ℤK is given. To illustrate the…

TLDR
The first seven chapters guide readers to the heart of current research in computational algebraic number theory, including recent algorithms for computing class groups and units, as well as elliptic curve computations, while the last three chapters survey factoring and primality testing methods.

Abstract.Let K be a biquadratic field. M.-N. Gras and F. Tanoé gave a necessary and sufficient condition that K is monogenic by using a diophantine equation of degree 4 [3]. We consider algebraic…
I and i
TLDR
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
