SUMMARY:Mathematical Sciences Department Discrete Mathematics Seminar: Brig
 itte Servatius\, WPI
DESCRIPTION:Title: NAC-colorings and rigidity of graphs\nAbstract: A NAC-co
 loring is a type of edge coloring of a graph G introduced by Grasegger\, L
 egersky and Schicho\, who showed that the existence of such a coloring cha
 racterizes the existence of a flexible realization of G in the plane with 
 positive edge lengths. We give a review of interesting results concerning 
 NAC-colorings and investigate NAC-colorings of combinatorial zeolites.
