Recursion in rsC is guarded and hence contractive in the usual sense. We take an equi-recursive view of recursion by equating rec x.σ with σ[rec x.σ/x]. We use α to range over N ∪ N , with the convention α = a if α = a, and α = a if α = a. We write α1.σ1 + α2.σ2 for binary external input/output choice and α1.σ1 α2.σ2 for binary internal input/output choice. They are both commutative by definition.
