A hierarchy theorem for the μ-calculus

  • Giacomo Lenzi
Session 2: Fairness, Domination, and the μ-Calculus
Part of the Lecture Notes in Computer Science book series (LNCS, volume 1099)


We consider the positive mu-calculus with successors PμS, namely a variant of Kozen's modal mu-calculus Lμ [9] where negation is suppressed and where the basic modalities are a sequence of successor operators l1,..., ln,4. In particular we are interested in the sublanguages of PμS determined by the value of the Emerson-Lei alternation depth
