A Saturation Method for the Modal Mu-Calculus with Backwards Modalities over Pushdown Systems (1006.5906v1)
Published 30 Jun 2010 in cs.FL and cs.LO
Abstract: We present an extension of an algorithm for computing directly the denotation of a mu-calculus formula X over the configuration graph of a pushdown system to allow backwards modalities. Our method gives the first extension of the saturation technique to the full mu-calculus with backwards modalities.
