Description | In this paper we study the model-checking problem for probabilistic pushdown automata (pPDA) and branching-time probabilistic logics PCTL and PCTL*. We show that model-checking pPDA against general PCTL formulae is undecidable, but we yield positive decidability results for the qualitative fragments of PCTL and PCTL*. For these fragments, we also give a complete complexity classification. |
