Kommentar zu [CPW11]
I see a lot of similarities with my dissertation [2] or [3].
- the morphisms in [1] are a restriction of place-preserving morphisms (definition 4.19 and definition 5.27, respectively in [2]).
- the concept of true morphisms [1], does not occur, however, the morphisms from an unfolding to the original net system (universal arrows) in [2] are true.
- Proposition 4 and 5 in [1] correspond to Lemma 7.40 in [2],
- Proposition 6 in [1] is used/proved in the proof of 7.41
- The unfolding in Theorem 1 [1] is the same as the unfolding in Proposition 7.41 [2] (as mentioned, the universal arrow is true)
