AbstractWe show that several reducibility notions coincide when applied to the Graph Isomorphism (GI) problem. In particular we show that if a set is many-one logspace reducible to GI, then it is in fact many-one
$ extsf{AC}^{0}$
reducible to GI. For the case of Turing reducibilities we show that for any k≥0 an
$ extsf{NC}^{k+1}$
reduction to GI can be transformed into an
$ extsf{AC}^{k}$
reduction to the same problem.
