Limitwise monotonic reducibility on sets and on pairs of sets
D. Kh. Zainetdinov Chair of Algebra and Mathematical Logic, Kazan (Volga Region) Federal University, 18 Kremlyovskaya str., Kazan, 420008 Russia
Abstract:
We study limitwise monotonic sets and pairs of sets. We investigate the properties of limitwise monotonic reducibility between sets and pairs of sets defined in terms of $\Sigma$-reducibility corresponding to initial segment of sets. In addition, we obtain a description of $\Sigma$-reducibility of families of a special form in terms of $lm$-reducibility. At the same time we show the relationship of concepts of $lm$-reducibility and $\Sigma$-reducibility between the pairs of sets.
Keywords:
computable functions, $\Sigma$-reducibility, $\Sigma^0_2$-sets, limitwise monotonic function, limitwise monotonic sets, limitwise monotonic reducibility, pair of sets, family of subsets of natural numbers.
