The Parallel-Sequential Duality : Matrices and Graphs (0709.4397v2)

Abstract: Usually, mathematical objects have highly parallel interpretations. In this paper, we consider them as sequential constructors of other objects. In particular, we prove that every reflexive directed graph can be interpreted as a program that builds another and is itself builded by another. That leads to some optimal memory computations, codings similar to modular decompositions and other strange dynamical phenomenons.
