Human Graph Theory A problem-solving, name-learning activity 1998 Summer Institute Participant Projects List of Participants Sum98 Staff ... Agenda The Math Forum's 1998 Summer Institute began at noon on the lawn outside the Swarthmore College guest house, Ashton House, with a graph theory game based on Toss and Sort (see also Graphs and Graph Theory ) designed to help the group learn each other's names and get acquainted. (Thanks to Mel Sprouse, who provided the photographs!) Each participant wrote his or her name on a piece of paper. Ken, Steve, and Dave then linked these pieces of paper, as well as two blank "nodes," with masking tape to form a graph with several cycles and dead ends. The following diagram is a reconstruction (we hope accurate) of this graph: Folks then randomly re-settled on a node that did not necessarily bear their own name. Our shared objective: move people along the paths of the graph, advancing one person at a time and only to connected unoccupied nodes, so that we achieved a state where each person stood at the node bearing her or his name. Ken helps start the game.

Over the last three decades, Neil Robertson, his Ph.D. students, and his collaborators have made fundamental contributions in the areas of graphs and matroids. As friends and colleagues of Neil, we are most pleased to announce that an international conference on "Advances in Graph and Matroid Theory" will be held in his honour on the occasion of his 65th birthday. The Ohio State University in Columbus, Neil's home institution for over thirty years, will host the conference on December 13-16, 2003. The conference will bring together the many active research collaborators of Neil Robertson. It is intended to foster numerous mathematical issues that are important to present-day graph theory. Fundamental topics in graph theory like connectivity, surface and spatial embeddings, well-quasi ordering, and chromatic theory find common links through their structural features. The close subject of matroid theory will also be represented at the conference.

Graph and Digraph Glossary A B C D ... V-Z Acyclic Digraph A digraph is acyclic if it contains no cycles Arc A directed edge of a digraph. Some authors use it as a synonym for an edge of a graph. Other synonyms for arc in a digraph are arrow, directed line, directed edge, and directed link. Arc List A representation of a digraph using the arcs of the digraph. Can be an unordered listing of the ordered pairs, or a pair of ordered lists with the starting vertex in one list and the ending vertex in the corresponding position of the second list. Adjacency Matrix A 0-1 square matrix whose rows and columns are indexed by the vertices. A 1 in the ij-th position of the matrix means that there is an edge (or arc ) from vertex i to vertex j. A indicates that there is no such edge (or arc). Can be used for both graphs and digraphs. Adjacency Structure A representation of a graph or digraph which lists, for each vertex, all the vertices that are adjacent to the given vertex. Adjacent Two vertices are adjacent if they are connected by an edge . We often call these two vertices neighbors . Two adjacent vertices: Bipartite Graph A graph is bipartite if the vertices can be partitioned into two sets, X and Y, so that the only

Sixth Czech-Slovak International Symposium on Combinatorics, Graph Theory, Algorithms and Applications Dedicated to Jarik Nesetril on the occasion of his 60 th birthday Prague, July 10-15, 2006 Home Photos Invited Speakers Social Events ... Contact Jarik Ne¹etøil is one of the best known Czech mathematicians. In today's world of narrowing specialization, the broadness of his research is astonishing. He strongly influenced the development of Discrete Mathematics in both our countries and created what is now often referred to as the Prague school of Combinatorics. The year of the 6th Czech-Slovak symposium is also the year of his 60th birthday. We are happy to celebrate his birthday by dedicating the symposium to him. The Conference is organized by the DIMATIA Center of Charles University, in cooperation with the majority of Czech and Slovak universities and academic institutions. It is the sixth in a series of symposia which started with the 1963 Smolenice meeting and continued in 1974, 1982 (Prague), 1990 (Prachatice) and 1998 (Prague) The program will be devoted (but not restricted) to subjects in contemporary Combinatorics and Graph Theory involving also relationships and applications in Algebra, Algorithms, Topology, Probability and Statistics, Mathematical Logic, Computer Science and other fields.

About graph theory (Topic) Graph theory is the branch of mathematics that concerns itself with graphs The concept of graphs is extraordinarily simple, which explains their wide applicability. It is usually agreed upon that graph theory proper was born in 1736, when Euler solutions of substantial problems over building machinery for its own sake. Graph theory representation bridges problem For quite long graph theory was regarded as a branch of topology concerned with -dimensional simplices, however this view has faded away. The only remainder of the topological past is the topological graph theory, a branch of graph theory that primarily deals with drawing of graphs on surfaces . The most famous achievement of topological graph theory is the proof of the four-color conjecture (every political map on the surface of a plane or a sphere can be colored into four colors given that each country consists of only one piece).
