Resumen: In this paper we study the complexity of the liveness problem for safe Elementary Object Nets (Eos). Object nets are Petri nets which have Petri nets as tokens. They are called elementary if the net system has a two levelled structure. The concept of safeness bounds the number of tokens which may reside on a place. We will use four different safeness definitions (first introduced in [10]) and show that the liveness problem is undecidable for safe(1) and safe(2) Eos and in Pspace for safe(3) and safe(4) Eos. We will devise an polynomial space algorithm for this problem and indeed for every property that can be expressed in the temporal logic CTL.[link]
