We consider highness in the context of computable structure theory and, particularly, the Scott rank of a structure. We define highness for Scott rank and highness for computably d…

Computable classifications of continuous, transducer, and regular functions
Johanna N. Y. Franklin, Rupert Hölzl, Alexander Melnikov +2
We develop a systematic algorithmic framework that unites global and local classification problems using index sets. We prove that the classification problem for continuous (binary…
