假设一个被广泛相信的关于算术级数中的最小素数的假设,我们证明了有限域(mathbb {F}_q)上具有(q)个元素的次数小于(n)的多项式可以在时间上相乘(O(n log q log(n log q),在(q)中一致。在相同的假设下,我们展示了如何在时间上乘以两个(n)位整数(O(n log n));该算法比配套论文[22]中的无条件算法稍微简单一些。我们的结果在有限数量磁带的图灵机模型中成立。
Assuming a widely believed hypothesis concerning the least prime in an arithmetic progression, we show that polynomials of degree less than ( n ) over a finite field ( mathbb {F}_q ) with ( q ) elements can be multiplied in time ( O (n log q log (n log q)) ) , uniformly in ( q ) . Under the same hypothesis, we show how to multiply two ( n ) -bit integers in time ( O (n log n) ) ; this algorithm is somewhat simpler than the unconditional algorithm from the companion paper [22]. Our results hold in the Turing machine model with a finite number of tapes.
