  Structural complexity theory. Constructs oracles in which \(\mathsf{BPP}\) (a probabilistic complexity class) and \(\mathsf{UP}\) (the class of problems with a unique "witness") contain languages that in a very strong sense are not contained in the other class. The conference version used the title "Probabilistic and unambiguous computation are incomparable".
