For a given graph G and vertices u, v in G let ,,,~ ~(.,~) G(-,,o) G~, o) denote the graph Gm ~ Va , ~s :, obtained from G by merging vertices u, v, adding edge (u, v), subdividing edge (u, v), contracting edge (u, v) of G, respectively. We give upper and lower bounds for the bandwidth of ~'~ ~(~'~)

Certain problems involving the coloring the edges or vertices of infinite graphs are shown to be undecidable. In particular, let G and H be finite 3-connected graphs, or triangles. Then a doubly-periodic infinite graph F is constructed such that the following problem is undecidable: For a coloring o
The relationship between the graphical invariants bandwidth and number of edges is considered. Bounds, some sharp and others improvements of known results, are given for the nznber of edges of graphs having a given bandwidth. An important invariant of undirected graphs having no loops or multiple e
