Solving a system of linear diophantine equations with lower and upper bounds on the variables [PDF]

open access: yes
We develop an algorithm for solving a system of diophantine equations with lower and upper bounds on the variables. The algorithm is based on lattice basis reduction. It first finds a short vector satisfying the system of diophantine equations, and a set

Exact Combinatorial Density of States for the Critical 1D Ising Model

open access: yesEntropy
This work presents an exact microcanonical combinatorial analysis of the one-dimensional antiferromagnetic Ising model. At the primary ground-state level crossing B/J=2, degeneracies follow the Fibonacci and Lucas sequences for open chains and periodic ...

Partitions, diophantine equations, and control systems [PDF]

open access: yes
[EN] Ordered partitions of elements of a reduced abelian monoid are defined and studied by means of the solutions of linear diophantine equations. Links to feedback classification of linear dynamical systems over certain commutative rings are given in ...
