This is the main motivation for the introduction of . of graphs, which are used to define a (more restricted) notion of equivalence among graph morphisms, direct derivations and graph derivations. The properties of the r

During the execution of a step, the machine instances perform in parallel a local transformation on the graph and are each replaced by a number of other machine instances. It is proved that the generic graph machines express

An existence theorem of pushouts in the category of relational structures and their partial morphisms is proved under a certian functorial condition, and it enables us to discuss single pushout rewritings of relational structures.

Context conditions are just items which have to be present in order for an event to take place, but which are not affected by the event. They are very useful for describing situations where different events share a comm
