Center node: "a traditional tree style tableau for ltl"
  Abstract: Propositional linear time temporal logic (LTL) is the standard temporal logic for computing applications and many reasoning techniques and tools have been developed for it. Tableaux for deciding satisfiability have existed since the 1980s. However, the tableaux for this logic do not look like traditional tree-shaped tableau systems and their processing is often quite complicated. We present a new simple traditional-style tree-shaped tableau for LTL and prove that it is sound and complete. As well as being simple to understand, to introduce to students and to use manually, it also seems simple to implement and promises to be competitive in its automation. It is particularly suitable for parallel implementations.

Connected through hyperedge HE-1 (induced by source paper "tableaux for policy synthesis for mdps with pctl constraints"):
  with members:
    - "a new rule for ltl tableaux"
    - "optimal control of mdps with temporal logic constraints"

Connected through hyperedge HE-2 (induced by source paper "a genetically modified hoare logic"):
  with members:
    - "model checking gene regulatory networks"
    - "negative circuits and sustained oscillations in asynchronous automata networks"
