Ernst Homburg,Anthony S. Travis function on that input.).We give a relativized negative answer to this question by exhibiting an oracle under which . functions are easy to compute but the polynomial-time hierarchy is infinite. We also show that relative to this same oracle, . and . functions are not computable in polynomial-time with an . oracle.
