    On the Chromatic Number of the Visibility Graph of a Set of Points in the Plane

  • Original language description

    The visibility graph $V(P)$ of a set of points $P$ in the plane is the graph with vertex set $P$ where two vertices $u$ and $v$ are adjacent if and only if there is no point from $P$ on the segment connecting $u$ with $v$. We study the chromatic number of $V(P)$ and show superpolynomial lower bound on the chromatic number in terms of clique number.

    O barevnosti viditelnostních grafů

  • Czech description

    Viditelnostní graf $V(P)$ množiny bodů v rovině $P$ je graf s vrcholy $P$, kde vrcholy $u$ a $v$ jsou spojené hranou právě když na úsečce spojující $u$ a $v$ neleží žádný jiný bod z $P$. V práci studujeme barevnost $V(P)$ a ukážeme super-polynomiální dolní mez na barevnost vzhledem ke klikovosti.
