Gauss Congruences in Algebraic Number Fields
In this miniature note we generalize the classical Gauss congruences for integers to rings of integers in algebraic number fields.

Finiteness theorems for algebraic tori over function fields
We present a number of finiteness results for algebraic tori (and, more generally, for algebraic groups with toric connected component) over two classes of fields: finitely generated fields and function fields of algebraic varieties over fields of type ...

In this paper, we find some inequalities which involve Euler’s function, extended Euler’s function, the function τ, and the generalized function τ in algebraic number fields.

Isomorphisms of algebraic number fields [PDF]
Let $\mathbb{Q}( )$ and $\mathbb{Q}( )$ be algebraic number fields. We describe a new method to find (if they exist) all isomorphisms, $\mathbb{Q}( ) \rightarrow \mathbb{Q}( )$. The algorithm is particularly efficient if the number of isomorphisms is one.

About the Entropy of a Natural Number and a Type of the Entropy of an Ideal
In this article, we find some properties of certain types of entropies of a natural number. We are studying a way of measuring the “disorder” of the divisors of a natural number. We compare two of the entropies H and H¯ defined for a natural number.

Constructions of Dense Lattices of Full Diversity
A lattice construction using Z-submodules of rings of integers of number fields is presented. The construction yields rotated versions of the laminated lattices A_n for n = 2,3,4,5,6, which are the densest lattices in their respective dimensions.

Prime Spectrum of the Ring of Adeles of a Number Field
Much is known about the adele ring of an algebraic number field from the perspective of harmonic analysis and class field theory. However, its ring-theoretical aspects are often ignored.

Some Properties of Extended Euler’s Function and Extended Dedekind’s Function
In this paper, we find some properties of Euler’s function and Dedekind’s function. We also generalize these results, from an algebraic point of view, for extended Euler’s function and extended Dedekind’s function, in algebraic number fields ...

All opinions are not equal: Toward a consensual approach to the development of drug policy
Abstract Drug policy has been subjected to much scrutiny from different stakeholder groups who present sometimes very different opinions on solutions to address a problem. Reconciling such differences, that are underpinned by both anecdotal and empirical evidence, is a priority yet to be fully achieved.

The $16$th Hilbert problem on algebraic limit cycles [PDF]
For real planar polynomial differential systems there appeared a simple version of the $16$th Hilbert problem on algebraic limit cycles: {\it Is there an upper bound on the number of algebraic limit cycles of all polynomial vector fields of degree $m ...
