Concurrent Kleene Algebra (CKA) was introduced by Hoare, Moeller, Struth and Wehrman in 2009 as a framework to reason about concurrent programs. Up until now, a description of the free model that corresponds to the CKA axioms was missing. Using a fixpoint construction, we show that the free model of the fragment of CKA with bounded parallelism consists of pomset languages that are downward-closed under the subsumption (linearisation) order.
