Abstract
We deal with relatives of GCH which are provable. In particular, we deal with rank version of the revised GCH. Our motivation was to find such results when only weak versions of the axiom of choice are assumed, but some of the results give us additional information even in ZFC. We also start to deal with pcf for pseudo-cofinality (in ZFC with little choice).
