Query: Proceedings 7th International Workshop on Computing with Terms and
  Graphs   This volume contains the proceedings of the Seventh International Workshop on
Computing with Terms and Graphs (TERMGRAPH 2013). The workshop took place in
Rome, Italy, on March 23rd, 2013, as part of the sixteenth edition of the
European Joint Conferences on Theory and Practice of Software (ETAPS 2013).
  Research in term and graph rewriting ranges from theoretical questions to
practical issues. Computing with graphs handles the sharing of common
subexpressions in a natural and seamless way, and improves the efficiency of
computations in space and time. Sharing is ubiquitous in several research
areas, as witnessed by the modelling of first- and higher-order term rewriting
by (acyclic or cyclic) graph rewriting, the modelling of biological or chemical
abstract machines, and the implementation techniques of programming languages:
many implementations of functional, logic, object-oriented, concurrent and
mobile calculi are based on term graphs. Term graphs are also used in automated
theorem proving and symbolic computation systems working on shared structures.
The aim of this workshop is to bring together researchers working in different
domains on term and graph transformation and to foster their interaction, to
provide a forum for presenting new ideas and work in progress, and to enable
newcomers to learn about current activities in term graph rewriting.
  These proceedings contain six accepted papers and the abstracts of two
invited talks. All submissions were subject to careful refereeing. The topics
of accepted papers range over a wide spectrum, including theoretical aspects of
term graph rewriting, concurrency, semantics as well as application issues of
term graph transformation.
