Seminar of Combinatorial Geometry
"Giuseppe Tallini"

Welcome to the page of the Combinatorics Seminar of the Department of Mathematics of the University Sapienza, Rome.

During the year 2007-2008 the seminar meets usually on Thursdays in Aula di Consiglio.

Next meetings:

Thursday; 5 June 2008, 3pm, Aula di Consiglio

• William M. Kantor (University of Oregon)
  Cycles in graphs
  

  I will discuss the following unpublished theorem of Conway, and generalizations: If a d-valent graph has an edge-transitive automorphism group G, then G has exactly d-1 orbits in its action on those ordered cycles of the graph that also are cycles of permutations in G.
