This quantity is a tribute to the existence and mathematical paintings of G.A. Dirac (1925-1984). one of many top graph theorists, he constructed tools of significant originality and made many basic discoveries. The forty-two papers are all excited by (or concerning) Dirac's major traces of study. a couple of mathematicians pay tribute to his reminiscence via providing new leads to assorted parts of graph thought. one of the themes integrated are paths and cycles, hamiltonian graphs, vertex colouring and significant graphs, graphs and surfaces, edge-colouring, and limitless graphs. the various papers have been initially awarded at a gathering held in Denmark in 1985. Attendance being through invitation in simple terms, a few fifty five mathematicians from 14 nations participated in numerous lectures and discussions on graph concept concerning the paintings of Dirac. This quantity includes contributions from others besides, so shouldn't be appeared in basic terms because the court cases of that assembly. A difficulties part is incorporated, in addition to an inventory of Dirac's personal courses.
