Branch-Well-Structured Transition Systems and Extensions

We propose a relaxation to the definition of well-structured transition systems (WSTS) while retaining the decidability of boundedness and non-termination.In this class, the well-quasi-ordered (wqo) dodge warlord for sale condition is relaxed such that it is applicable only between states that are reachable one from another.Furthermore, the monotony condition is relaxed in the same way.While this retains the decidability of non-termination and boundedness, it appears that the coverability problem is undecidable.

To this end, we read more define a new notion of monotony, called cover-monotony, which is strictly more general than the usual monotony and still allows us to decide a restricted form of the coverability problem.
