Abstract: | It is shown here that if NC = P , the NC hierarchy collapses. We give two proofs for this. From the point of view of a circuit for circuit evaluation, the assumption that NC = P implies that any polynomial size circuit can be transduced into a polynomial size and poly‐log depth circuit. Such a parallelization property can be applied not only for uniform circuits but also for nonuniform circuits. This interesting property suggests that the assumption NC = P would be false. © 2007 Wiley Periodicals, Inc.
