Abstract:
We extend the concept of graph representations modulo integers introduced by Erdos and
Evans to graph representations over finite rings and generalize it to representations of signed
graphs. We introduce several representation numbers and product dimensions of graphs and
signed graphs and compute these quantities for a few special classes of signed graphs
