Research in graph term rewriting is being done in regard to functional language implementation. Have Category Theoretic methods been applied to graph term rewriting research? If so, can someone point me at papers?
To my best knowledge, Fabio Gadducci has, for some time now, been applying category-theoretic structures to graph term rewriting, and has written a couple of relevant survey papers which feature extensive bibliographic references. I believe these papers may be found in his home page (http://www.di.unipi.it/~gadducci/) even though his links may seem a bit cryptic at first. My understanding of your question is that you're interested in rewriting graphs which encode the structure of terms in some signature (or the structure of program terms in some programming language). If, instead, it is the rewriting of graphs (independent of specific interpretations) or of programs in visual languages that you are interested in, then I would be happy to provide more specific pointers, as the latter area of research is closer to my own interests. -- Konstantinos Tourlas Tel. : 0131-650-5162 Rm 1404, JCMB, The University of Edinburgh, e-mail : kxt@dcs.ed.ac.uk King's Buildings, Edinburgh, EH9 3JZ UK
