On independence domination
Wing-Kai Hon, Ton Kloks, Hsiang Hsuan Liu +2
Let G be a graph. The independence-domination number is the maximum over all independent sets I in G of the minimal number of vertices needed to dominate I. In this paper we invest…
On retracts, absolute retracts, and folds in cographs
Ton Kloks, Yue-Li Wang
Let G and H be two cographs. We show that the problem to determine whether H is a retract of G is NP-complete. We show that this problem is fixed-parameter tractable when parameter…
A note on "Folding wheels and fans."
Ton Kloks, Yue-Li Wang
In S.Gervacio, R.Guerrero and H.Rara, Folding wheels and fans, Graphs and Combinatorics 18 (2002) 731-737, the authors obtain formulas for the clique numbers onto which wheels and…
Folding graphs
Ton Kloks, Yue-Li Wang
Let G be a graph. Consider two nonadjacent vertices x and y that have a common neighbor. Folding G with respect to x and y is the operation which identifies x and y. After a maxima…
