The inflation G I of a graph G with n(G) vertices and m(G) edges is obtained by replacing every vertex of degree d of G by a clique K d . We study the lower and upper irredundance parameters ir and IR of an inflation. We prove in particular that if Ξ³ denotes the domination number of a graph, Ξ³(G I )
## Abstract A circularβarc graph is the intersection graph of a family of arcs on a circle. A characterization by forbidden induced subgraphs for this class of graphs is not known, and in this work we present a partial result in this direction. We characterize circularβarc graphs by a list of minim
