SUMMARY:Dong Yeap Kang (강동엽)\, Fragile minor-monotone parameters under random edge perturbation
DESCRIPTION:We investigate how minor-monotone graph parameters change if we add a few random edges to a connected graph $H$. Surprisingly\, after adding a few random edges\, its treewidth\, treedepth\, genus\, and the size of a largest complete minor become very large regardless of the shape of $H$. Our results are close to best possible for various cases. We also discuss analogous results for randomly perturbed bipartite graphs as well as the size of a largest complete odd minor in randomly perturbed graphs.
