Center node: "on the complexity of probabilistic justification logic"
  Abstract: Probabilistic justification logic is a modal logic with two kind of modalities: probability measures and explicit justification terms. We present a tableau procedure that can be used to decide the satisfiability problem for this logic in polynomial space. We show that this upper complexity bound is tight.

Connected through hyperedge HE-1 (induced by source paper "the complexity of satisfiability in non iterated and iterated probabilistic logics"):
  with members:
    - "probability logic"
    - "the complexity of non iterated probabilistic justification logic"
    - "nexp completeness and universal hardness results for justification logic"

Connected through hyperedge HE-2 (induced by source paper "the complexity of non iterated probabilistic justification logic"):
  with members:
    - "nexp completeness and universal hardness results for justification logic"
    - "justifications for common knowledge"
