Additively indecomposable quadratic forms over biquadratic and simplest cubic fields

Simona Fryšová, Magdaléna Tinková

In this paper, we study additively indecomposable quadratic forms over real biquadratic and simplest cubic fields. In particular, we show that over these fields, we can always find…

Linear constellations in primes with arithmetic restrictions

Christopher Frei, Joachim König, Magdaléna Tinková

We prove analogues of the theorem of Green and Tao on linear constellations in primes, in which the primes under consideration are restricted by certain arithmetic conditions. Our…

Sums of two units in number fields

Magdaléna Tinková, Robin Visser, Pavlo Yatsyna

Let be a number field with ring of integers . Let be the set of positive integers such that there exist units $\varepsilon, δ\in \mathcal{O}…

Additively indecomposable quadratic forms over totally real number fields

Magdaléna Tinková, Pavlo Yatsyna

We give an upper bound for the norm of the determinant of additively indecomposable, totally positive definite quadratic forms defined over the ring of integers of totally real num…

Additive structure of non-monogenic simplest cubic fields

Daniel Gil-Muñoz, Magdaléna Tinková

We consider Shanks' simplest cubic fields for which the index of a root of the defining parametric polynomial is . For them, we study t…

Arithmetic of cubic number fields: Jacobi-Perron, Pythagoras, and indecomposables

Vítězslav Kala, Ester Sgallová, Magdaléna Tinková

We study a new connection between multidimensional continued fractions, such as Jacobi--Perron algorithm, and additively indecomposable integers in totally real cubic number fields…
