We introduce PHFL, a probabilistic extension of higher-order fixpoint logic, which can also be regarded as a higher-order extension of probabilistic temporal logics such as PCTL and the mu(p)-calculus. We show that PHFL is strictly more expressive than the mu(p)-calculus, and that the PHFL model-checking problem for finite Markov chains is undecidable even for the mu-only, order-1 fragment of PHFL. Furthermore the full PHFL is far more expressive: we give a translation from Lubarsky's mu-arithmetic to PHFL, which implies that PHFL model checking is Pi(1)(1)-hard and Sigma(1)(1) -hard. As a positive result, we characterize a decidable fragment of the PHFL model-checking problems using a novel type system. |
