Cubes of integral vectors in dimension four

A system of $m$ nonzero vectors in $\mathbb{Z}^n$ is called an $m$-icube if they are pairwise orthogonal and have the same length. The paper describes $m$-icubes in $\mathbb{Z}^4$ for $2\le m\le 4$

Cubic sublattices

A sublattice of the three-dimensional integer lattice Z is called cubic sublattice if there exists a basis of the sublattice whose elements are pairwise orthogonal and of equal lengths. We show that

A sum of three nonunit squares of integers

We say a positive integer is a sum of three nonunit squares if it is a sum of three squares of integers other than one. In this article, we find all integers which are sums of three nonunit squares

Ehrhart polynomial for lattice squares, cubes and hypercubes

For squares and cubes and hypercubes, the Ehrhart polynomial is found, one of the coefficients is computed and there exists a simple linear relation between the other two unknown coefficients.

On the Representations of xy + yz + ZX

It is shown that there are at most 19 integers that are not of the form xy + yz + xz with x, y, z ≥ 1 and the remaining possibility must be greater than 1011 and cannot occur if the Generalized Riemann Hypothesis is assumed.
