This paper is a survey of results on countable families with natural degree spectra. These results were obtained by a modification of the methodology proposed by Wechner, who first found a family of sets with the spectrum consisting precisely of nonz

Abstract We are studying the punctual structures, i.e., the primitive recursive structures on the whole set of integers. The punctual categoricity relative to a computable oracle $$f$$ means that between any two punctual copies of a structure there i

It is well-known that every c.e. Turing degree is the degree of categoricity of a rigid structure. In this work we study the possibility of extension of this result to properly 2-c.e. degrees. We found a condition such that if a $$\Delta^{0}_{2}$$ -d

We construct the example of an admissible set $$\mathbb{A}$$ such that there exists a positive computable $$\mathbb{A}$$-numbering of the family of all $$\mathbb{A}$$-c.e. sets, whereas any negative computable $$\mathbb{A}$$-numberings are absent.
