Center node: "confluence and convergence in probabilistically terminating reduction systems"
  Abstract: Convergence of an abstract reduction system (ARS) is the property that any derivation from an initial state will end in the same final state, a.k.a. normal form. We generalize this for probabilistic ARS as almost-sure convergence, meaning that the normal form is reached with probability one, even if diverging derivations may exist. We show and exemplify properties that can be used for proving almost-sure convergence of probabilistic ARS, generalizing known results from ARS.

Connected through hyperedge HE-1 (induced by source paper "confluence in probabilistic rewriting"):
  with members:
    - "the geometry of parallelism classical probabilistic and quantum effects"
    - "probabilistic operational semantics for the lambda calculus"
    - "confluence results for a quantum lambda calculus with measurements"
    - "a lambda calculus for quantum computation with classical control"
