Sensoria Bibliography Site An Algebra of Hierarchical Graphs
Roberto Bruni, Fabio Gadducci, Alberto Lluch Lafuente
abstract:
We define an algebraic theory of hierarchical graphs, whose
axioms characterise graph isomorphism: two terms are equated exactly
when they represent the same graph. Our algebra can be understood as a
high-level language for describing graphs with a node-sharing, embedding
structure, and it is then well suited for defining graphical representations
of software models where nesting and linking are key aspects.
