Representations of Cyclic Groups in Rings of Integers, I
The Annals of Mathematics, 1962Let Gk be a cyclic group of order k, and let ZGk denote its group ring over the ring Z of rational integers. We denote by n(ZGk) the number of non-isomorphic indecomposable left ZGk-modules having finite Z-bases. In 1938 Diederichsen [2] proved that n(ZG,) is finite for p a rational prime, and gave an incorrect proof that n(ZG4) is infinite.

Towards Hilbert’s tenth problem for rings of integers through Iwasawa theory and Heegner points
Mathematische Annalen, 2019For a positive proportion of primes p and q , we prove that $${\mathbb {Z}}$$ Z is Diophantine in the ring of integers of $${\mathbb {Q}}(\root 3 \of {p},\sqrt{-q})$$ Q ( p 3 , - q ) .

Rings: Applications of the integers
1976In this chapter we assemble some results on rings which we obtain by using a specific knowledge of the natural numbers and the integers. We begin the chapter with some work refining our knowledge of finite and infinite sets. We then routinely study some theorems extending the associative, commutative, and distributive laws to any finite number of ...

UNDECIDABILITY OF FAMILIES OF RINGS OF TOTALLY REAL INTEGERS
International Journal of Number Theory, 2008Let ℤtrbe the ring of totally real integers, Gal(ℚ) the absolute Galois group of ℚ, and e a positive integer. For each σ = (σ1,…,σe) ∈ Gal (ℚ)elet ℤtr(σ) be the fixed ring in ℤtrof σ1,…,σe. Then, the theory of all first order sentences θ that are true in ℤtr(σ) for almost all σ ∈ Gal (ℚ)e(in the sense of the Haar measure) is undecidable.

Explicit Polynomial Generators for the Ring of Quasisymmetric Functions over the Integers
, 2004In (Hazewinkel in Adv. Math. 164:283–300, 2001, and CWI preprint, 2001) it has been proved that the ring of quasisymmetric functions over the integers is free polynomial.
