On the expressiveness of communication channels for object nets.
Fundamenta Informaticae, 93(1-3):205-219, 2009.
Abstract: In this work we present object net systems, i.e. Petri nets with nets as token objects, which are equipped with channels that allow to transfer net-tokens in the vertical dimension of the nested marking. These channels are a modelling element powerful enough to describe a direct simulation of counter programs which shows that typical net problems like boundedness, coverability, and reachability are undecidable.
