Decidability of strong bisimulation of basic parallel processes using Hilbert's basis theorem

We will apply some algebraic results, namely Hilbert's basis theorem and Grr obner bases, to get a diierent technique for proving decidability of strong bisimulation of basic parallel processes.

On the Complexity of Bisimulation Problems for Basic Parallel Processes

Strong bisimilarity of Basic Parallel Processes (BPP) is decidable, but the best known algorithm has non-elementary complexity [7]. On the other hand, no lower bound for the problem was known. We show that strong bisimilarity of BPP is co-NP-hard. Weak bisimilarity of BPP is not known to be decidable, but an NP lower bound has been shown in [31]. We improve this result by showing that weak bisi...

Non-interleaving bisimulation equivalences on Basic Parallel Processes

We show polynomial time algorithms for deciding hereditary history preserving bisimilarity (in O(n logn)) and history preserving bisimilarity (in O(n)) on the class Basic Parallel Processes. The latter algorithm also decides a number of other non-interleaving behavioural equivalences (e.g., distributed bisimilarity) which are known to coincide with history preserving bisimilarity on this class....

Weak Bisimulation and Model Checking for Basic Parallel Processes

Basic Parallel Processes (BPP) are a natural subclass of CCS innnite-state processes. They are also equivalent to a special class of Petri nets. We show that unlike for general Petri nets, it is decidable if a BPP and a nite-state system are weakly bisimilar. To the best of our knowledge, this is the rst decidability result for weak bisimulation and a non-trivial class of innnite-state systems....
