Abstract
We present a simple and natural deductive formalism μPDL for propositional dynamic logic for recursive procedures, including simultaneous recursion. Though PDL with recursive programs is known to be highly undecidable, natural deductive formalisms for it are of substantial interest, because they distill the essential logical components of recursive procedures. We also show that Pratt-Kozen’s μ-Calculus, in which fixpoints are taken over formulas rather than programs, is interpretable in μ PDL.
