A jump inversion theorem for the semilattices of $\Sigma$-degrees
A. I. Stukachev Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
For the semilattices of $\Sigma$-degrees of structures, we prove an analogue of the jump inversion theorem. As a corollary, we get similar result for the semilattices of degrees of of presentability of countable structures.
Keywords:
computability, computable structures, admissible sets.
