Title
Dominating sets inducing large components in maximal outerplanar graphs.
Abstract
For a maximal outerplanar graph G of order n at least three, Matheson and Tarjan showed that G has domination number at most n/3. Similarly, for a maximal outerplanar graph G of order n at least five, Dorfling, Hattingh, and Jonck showed, by a completely different approach, that G has total domination number at most 2n/5 unless G is isomorphic to one of two exceptional graphs of order 12. We present a unified proof of a common generalization of these two results. For every positive integer k, we specify a set Hk of graphs of order at least 4k+4 and at most 4k2-2k such that every maximal outerplanar graph G of order n at least 2k+1 that does not belong to Hk has a dominating set D of order at most kn2k+1 such that every component of the subgraph G[D] of G induced by D has order at least k.
