Abstract
We investigate properties of the relativized AC and NC hierarchies in their DLOGTIME-, respectively, ALOGTIME-uniform setting and show that these hierarchies can be characterized in terms of adaptive reducibili ty in deterministic (poly)logarithmic time, i.e. in time O(log n)(i) f or i greater than or equal to 0. Using this characterization, we subst antially generalize various previous results concerning the structure of the two hierarchies.
