Abstract
Propositional dynamic logic (PDL) is complete but not compact. As a consequence, strong completeness (the property Γ |= φ ⇒ Γ |- φ) does not hold for the standard finitary axiomatisation. In this paper, we present an infinitary proof system of PDL and prove strong completeness. The result is extended to epistemic logic with common knowledge.
