The chromatic number of 3-stable Kneser graphs

open access: yes
For an integer $s \ge 2$, a subset $S \subseteq [n]$ is {\em $s$-stable} if $\min \{j - i, n + i - j\}\ge s$ for every $i,j \in S$ with ...

Neighborhood Complexes of Stable Kneser Graphs

Combinatorica, 2003
The stable Kneser graph \(\mathrm{SG}_{n,k}\) consists of those \(n\)-element subsets of the cyclically ordered set \(\{1,\dots,2n+k\}\) which contain no 2 consecutive elements, with two such \(n\)-sets joined if and only if they are disjoint. It is shown that the neighborhood complex of \(\mathrm{SG}_{n,k}\) is homotopy equivalent to the sphere ...

Cohomology Rings of Subspace Arrangements and the Topology of Stable Kneser Graphs

2000
Subspace Arrangements A subspace arrangement is a finite family of subspaces of euclidean space R^n. The combinatorics and topology of complements of such arrangements are well studied objects and enjoy a long history of research. Chapter 1 of the present thesis gives a complete description of the multiplication of the integral cohomology ring of a ...
