# True Parallel Graph Transformations: an Algebraic Approach Based on Weak Spans

17 Apr 2019Thierry Boy de la TourRachid Echahed

We address the problem of defining graph transformations by the simultaneous application of direct transformations even when these cannot be applied independently of each other. An algebraic approach is adopted, with production rules of the form $L\xleftarrow{l}K \xleftarrow{i} I \xrightarrow{r} R$, called weak spans... (read more)
