Seminal graph theory

WebStructural graph theory provides powerful tools for designing efficient algorithms in large families of graphs. The seminal work about the structure of graphs is Robertson and Seymour’s Graph Minors series of over twenty papers over the past twenty years. From this work, particularly the decomposition theorem for? Work done while at MIT. WebWe strengthen the structural results from the seminal Graph Minor Theory of Robertson and Seymour in the case of apex-minor-free graphs, showing that apices can be made adjacent only to vortices if we generalize the notion of vortices to “quasivortices” of bounded treewidth, proving a conjecture from [10].

A graph which contains a closed eulerian trail is called eulerian.Euler showed that the graph G of Fig. 8b has no eulerian trail. For a graph to have such a trail, it is clear that the graph must be connected and that each vertex, except for possibly the first and last vertex …

Weblems in graph theory. At the beginning of the 1980s, Neil Robertson and Paul Seymour developed the theory of graph minors in a series of twenty long papers. It took twenty-one years [2, 3] to publish this seminal work, which had a tremendous impact not only on various branches of graph theory but also on many other areas, most notably ... WebRobertson and Seymour developed the seminal Graph Minor Theory over the past two decades. This breakthrough in graph structure theory tells us that a very wide family of graph classes (anything closed under deletion and contraction) have a rich structure similar to planar graphs.

In the mathematical field of graph theory, a semi-symmetric graph is an undirected graph that is edge-transitive and regular, but not vertex-transitive. In other words, a graph is semi-symmetric if each vertex has the same number of incident edges, and there is a symmetry taking any of the graph's edges to any other ...
