Characterizing Programming Systems Allowing Program Self-reference, analogs of programming languages. In an . in which the . form of Kleene’s Recursion Theorem (.) holds, it is possible to construct, algorithmically, from an arbitrary algorithmic task, a self-referential program that, in a sense, creates a self-copy and then performs that task on the self-copy.

Pseudojump Operators and , Classes, . is Medvedev complete, then there exists . ∈ . with .. We examine the consequences when .. is Turing incomparable with .. for . ≠ . in . and when . for all .,. ∈ .. Finally, we give a characterization of the jump in terms of . classes.向下 发表于 2025-3-24 00:52:37

Magnetic Structure in Chaotic Flowsfirst three levels of the hierarchy, or they are not even Borel measurable at all. In some cases the effective Borel measurability depends on further properties of the underlying metric spaces, such as effective local compactness and effective local connectedness.CREEK 发表于 2025-3-24 17:46:18
