主讲内容:

  Let n, k and t be integers with $1\leq t< k \leq n$. The generalized Kneser graph $K(n,k,t)$ is a graph whose vertices are the $k$-subsets of a fixed n-set, where two k-subsets A and B are adjacent if $|A\cap B|<t$. The graph $K(n,k,1)$ is the well-known Kneser graph. The treewidth of a graph is an important invariant in structural and algorithmic graph theory. In this talk, we consider the treewidth of the generalized Kneser graphs.
