In contrast to a previous attempt based on 2-categories, the use of bi-categories allows to define rewriting on concrete graphs. Thus, the problem of composition of isomorphism classes of rewriting sequences is avoided. Moreover, as a first step towards the recovery of the full expressive power of the formalism via a purely algebraic description, the concept of disconnected rules is introduced, i.e., rules whose interface graphs are made of disconnected nodes and edges only. It is proved that, under reasonable assumptions, rewriting via disconnected rules enjoys similar concurrency properties like in the classical approach.","lang":"eng"}],"intvolume":" 29","volume":29,"page":"80-100","year":"1999","type":"conference","publication":"Proceedings of the 8th Conference on Category Theory and Computer Science (CTCS 1999), Edinburgh (UK)","status":"public","citation":{"bibtex":"@inproceedings{Gadducci_Heckel_Llabrés_1999, series={Electronic Notes in Theoretical Computer Science}, title={A Bi-Categorical Axiomatisation of Concurrent Graph Rewriting}, volume={29}, DOI={http://dx.doi.org/10.1016/S1571-0661(05)80309-3}, booktitle={Proceedings of the 8th Conference on Category Theory and Computer Science (CTCS 1999), Edinburgh (UK)}, publisher={Elsevier}, author={Gadducci, Fabio and Heckel, Reiko and Llabrés, Mercé}, year={1999}, pages={80–100}, collection={Electronic Notes in Theoretical Computer Science} }","chicago":"Gadducci, Fabio, Reiko Heckel, and Mercé Llabrés. “A Bi-Categorical Axiomatisation of Concurrent Graph Rewriting.” In *Proceedings of the 8th Conference on Category Theory and Computer Science (CTCS 1999), Edinburgh (UK)*, 29:80–100.
