A Categorical Semantics for Guarded Petri Netscategorical semantics for Petri nets with guards. This comes in two flavors: Deterministic and with side-effects. Using the Grothendieck construction, we show how the guard semantics can be internalized in the net itself.

Genetics

Unfolding Symbolic Attributed Graph Grammarsis crucial to their use in modelling interfaces of services and components as well as the evolution of complex systems and networks. However, the established concurrent semantics of graph grammars by unfolding does not cover attributed grammars. We develop a theory of unfolding for attributed graph

Antagonism

Single Pushout Rewriting in Comprehensive Systemss, SPO’s applicability depends on the durability of pushouts after this transition. There is a wide range of work on the question when pushouts exist in categories with partial morphisms starting with the pioneering work of L?we and Kennaway and ending with an essential characterisation in terms of

Initial Conflicts for Transformation Rules with Nested Application Conditionsh ACs, conflicts are in general neither inherited from a bigger context any more, nor is it possible to find a finite and complete subset of finite conflicts as illustrated for the category of graphs. We define initial conflicts to be special so-called symbolic transformation pairs, and show that th
