We study the relation of autoreducibility and mitoticity for polylog-space many-one reductions and log-space many-one reductions. For polylog-space these notions coincide, while proving the same for log-space is out of reach. More precisely, we show the following results with respect to nontrivial sets and many-one reductions:1. polylog-space autoreducible ⇔ polylog-space mitotic, 2. log-space mitotic ⇒ log-space autoreducible ⇒ (log n · log log n)-space mitotic, 3. relative to an oracle, log-space autoreducible log-space mitotic.The oracle is an infinite family of graphs whose construction combines arguments from Ramsey theory and Kolmogorov complexity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
