Talk:Computable isomorphism

question
Is there a standard symbol for this relation? Like isomorphism-subscript-c? —Preceding unsigned comment added by 128.100.216.124 (talk) 20:00, 27 April 2011 (UTC)


 * In the context of computability theory two sets $$A;B \subseteq \N$$ which are recursively isomorphic are often denoted $$A \equiv B$$. But this may be confused with the symbol of the congruence relation on the set of integers. -- 86.56.98.28 (talk) 22:55, 28 May 2013 (UTC)
