Vertex magic total labeling of Cartesian products of some regular VMT regular graphs and even cyclesTalk on Gratko seminar. AbstractA vertexmagic total labeling of a graph G(V,E) is defined as onetoone mapping from the set of integers {1,2,...,V+E} to V union E with the property that the sum of the label of a vertex and the labels of all edges incident to this vertex is the same constant for all vertices of the graph. In the talk we present some techniques for constructing vertex magic total labelings of Cartesian products of even cycles and some vertex magic total regular graphs with additional properties. Talk given atGratko seminar at University of Minnesota Duluth, (September 17th, 2003).
