Abstract

We introduce the definition of local structures as description of computations to recognize strings and characterize families of Chomsky’s hierarchy in terms of projection of frontiers of local sets of structures. Then we consider particular grid structures we call bounded-grids and study the corresponding family of string languages by proving some closure properties and giving several examples.
