Center node: "on termination for faulty channel machines"
  Abstract: A channel machine consists of a finite controller together with#R##N#   several fifo channels; the controller can read messages from the#R##N#   head of a channel and write messages to the tail of a channel.  In#R##N#   this paper, we focus on channel machines with insertion errors,#R##N#   i.e., machines in whose channels messages can spontaneously appear.#R##N#   Such devices have been previously introduced in the study of Metric#R##N#   Temporal Logic.  We consider the termination problem: are all the#R##N#   computations of a given insertion channel machine finite?  We show#R##N#   that this problem has non-elementary, yet primitive recursive#R##N#   complexity.
