We show the following results regarding complete sets. - NP-complete sets and PSPACE-complete sets are many-one autoreducible. - Complete sets of any level of PH, MODPH, or the Boolean hierarchy over NP are many-one autoreducible. - EXP-complete sets are many-one mitotic. - NEXP-complete sets are weakly many-one mitotic. - PSPACE-complete sets are weakly Turing-mitotic. - If one-way permutations and quick pseudo-random generators exist, then NP-complete languages are m-mitotic. - If there is a tally language in NP ∩ coNP - P, then, for every ε > 0, NP-complete sets are not 2n(1+ε)- immune. These results solve several of the open questions raised by Buhrman and Torenvliet in their 1994 survey paper on the structure of complete sets.
