Abstract The ntcc process calculus is a timed concurrent constraint programming (ccp) model equipped with a ﬁrst-order linear-temporal logic (LTL) for expressing process speciﬁcations. A typical behavioral observation in ccp is the strongest postcondition (sp). The ntcc sp denotes the set of all inﬁnite output sequences that a given process can exhibit. The veriﬁcation problem is then whether the sequences in the sp of a given process satisfy a given ntcc LTL formula. This paper presents new positive decidability results for timed ccp as well as for LTL. In particular, we shall prove that the following problems are decidable: (1) The sp equivalence for the so-called locally-independent ntcc fragment; unlike other fragments for which similar results have been published, this fragment can specify inﬁnite-state systems. (2) Veriﬁcation for locally-independent processes and negation-free ﬁrst-order formulae of the ntcc LTL. (3) Implication for such formulae. (4) Satisﬁabili...
