Abstract

We show that several formulas of a temporal logic can beverified using the coverability graph of the underlying system. Ofcourse, the procedure is not capable of verifying all formulae, sincealready the reachability problem for (unbounded) Petri nets iscomputationally hard. Thus, the procedure returns true, false, orunknown for a query. The formulae that can be verified cover most ofthe well known standard properties which have been listed in thecontext of coverability graph analysis so far.
