Quantitative Causality in Membrane Systems
We define and study specific and general causality in terms of multisets of objects and of multisets of rules. We relate the two notions of causality, and provide characterizations for each of them. We give an inductive method of obtaining the general causes of a multiset of objects, and use the general causes of a multiset v to find all the multisets u from which v can be obtained in a single evolution step.
