Abstract:
We study a family of distance graphs in $\mathbb R^n$. We present bounds for independence numbers which are asymptotically tight as $n\to\infty$. We substantially improve upper bounds on chromatic numbers of these graphs, and in a number of cases we give explicit constructions of independence sets.
