On the C.E. degrees realizable in II⁰₁ classes
We study for each computably bounded Π01 class P the set of degrees of c.e. paths in P. We show, amongst other results, that for every c.e. degree a there is a perfect Π01 class where all c.e. members have degree a. We also show that every Σ03 set of c.e. indices is realized in some perfect Π01 clas...
