Embeddings of Computable Structures

Asher M. Kach, Oscar Levin, Reed Solomon
2010 Notre Dame Journal of Formal Logic  
We study what the existence of a classical embedding between computable structures implies about the existence of computable embeddings.  ...  In particular, we consider the effect of fixing and varying the computable presentations of the computable structures.  ...  If S is a computably categorical structure, then the class of computable presentations of S has the strong embedding property.  ...

Computable embeddings for pairs of linear orders [article]

Nikolay Bazhenov, Hristo Ganchev, Stefan Vatev
2021 arXiv   pre-print
We study computable embeddings for pairs of structures, i.e. for classes containing precisely two non-isomorphic structures.  ...  Surprisingly, even for some pairs of simple linear orders, computable embeddings induce a non-trivial degree structure.  ...  On the other hand, our results will show that computable embeddings induce a non-trivial degree structure for two-element classes consisting of computable structures.  ...
