Graph Minors,eorems that mathematics has to offer: .. This ., inconspicuous though it may look at first glance, has made a fundamental impact both outside graph theory and within. Its proof, due to Neil Robertson and Paul Seymour, takes well over 500 pages.

Conflagration

Matching Covering and Packing,p all its vertices in this way? If not, how can we be sure that this is indeed impossible? Somewhat surprisingly, this basic problem does not only lie at the heart of numerous applications, it also gives rise to some rather interesting graph theory.

Connectivity, all it says is that we need at least . vertices to disconnect it. The following definition—which, incidentally, implies the one above—might have been more descriptive: ‘a(chǎn) graph is . if any two of its vertices can be joined by . independent paths’.

Colouring,scheduled for committee meetings of a parliament if every committee intends to meet for one day and some members of parliament serve on several committees? How can we find a school timetable of minimum total length, based on the information of how often each teacher has to teach each class?

Infinite Graphs,, but then moves on in several directions to display both the breadth and some of the depth that this field has to offer. Our overall theme will be to highlight the typical kinds of phenomena that will always appear when graphs are infinite, and to show how they can lead to deep and fascinating prob
