Computable isomorphism

In computability theory two sets A , B {\displaystyle A,B} of natural numbers are computably isomorphic or recursively isomorphic if there exists a total computable and bijective function f : N → N {\displaystyle f\colon \mathbb {N} \to \mathbb {N} } such that the image of f {\displaystyle f} restricted to A ⊆ N {\displaystyle A\subseteq \mathbb {N} }…
