The study of expressiveness of concurrent processes via session types opens a connection between linear logic and mobile processes, grounded in the rigorous logical background of propositions-as-types. One such study includes a notion of parametric session polymorphism, which connects session typed processes with rich higher-order functional computations. This work proposes a novel and non-trivial application of session parametricity – an encoding of inductive and coinductive session types, justified via the theory of initial algebras and final co-algebras using a processes-as-morphisms viewpoint. The correctness of the encoding (i.e. universality) relies crucially on parametricity and the associated relational lifting of sessions.
