Gassert’s paper ”A NOTE ON THE MONOGENEITY OF POWER MAPS” is cited at least by 17 papers in the context of monogeneity of pure number fields despite some errors that it contains and remarks on it. In this note, we point out some of these errors, and make some improvements on it.

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.
A NOTE ON THE MONOGENEITY OF POWER MAPS
Let φ(x) = xd − t ∈ Z[x] be an irreducible polynomial of degree d ≥ 2, and let θ be a root of φ. The purpose of this paper is to establish necessary and sufficient conditions for φ(x) to be
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.
On a Theorem of Ore
Abstract O. Ore (Math. Ann. 99, 1928, 84–117) developed a method for obtaining the absolute discriminant and the prime-ideal decomposition of the rational primes in a number field K. The method,
Newton polygons of higher order in algebraic number theory
We develop a theory of arithmetic Newton polygons of higher order, that provides the factorization of a separable polynomial over a p-adic eld, together with relevant arithmetic information about the
Binomial Thue equations and power integral bases in pure quartic fields
It is a classical problem in algebraic number theory to decide if a number field admits power integral bases and further to calculate all generators of power integral bases. This problem is
NEWTON POLYGONS AND p-INTEGRAL BASES OF QUARTIC NUMBER FIELDS
Let p be a prime number. In this paper we use an old technique of O. Ore, based on Newton polygons, to construct in an efficient way p-integral bases of number fields defined by p-regular equations.
On power integral bases for certain pure number fields defined by x24 – m
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,

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.
