More on Numbers and Graphs

Abstract

In this note we revisit a "ring of graphs" Q in which the set of finite simple graphs N extend the role of the natural numbers and the signed graphs Z extend the role of the integers. We point out the existence of a norm which allows to complete Q to a real or complex Banach algebra R or C.
