有限域扩张中乘法张量秩的新的一致渐近上界

New uniform and asymptotic upper bounds on the tensor rank of multiplication in extensions of finite fields

Julia Pieltant, Hugues Randriam

摘要:

我们获得了新的统一上界的(不一定对称)张量秩的乘法在有限域$\F_q$的任何素数或素数幂$q\geq2$的扩展,而且这些统一的界限导致新的渐近界以及。此外,我们还给出了纯粹的渐近界,这是更好地使用家庭的Shimura曲线定义在$\F_q$,与最佳比率的$\F_{q^t}$合理的地方,他们的属,其中$q^t$是一个广场。

英文摘要:

We obtain new uniform upper bounds for the (non necessarily symmetric) tensor rank of the multiplication in the extensions of the finite fields $\F_q$ for any prime or prime power $q\geq2$; moreover these uniform bounds lead to new asymptotic bounds as well. In addition, we also give purely asymptotic bounds which are substantially better by using a family of Shimura curves defined over $\F_q$, with an optimal ratio of $\F_{q^t}$-rational places to their genus where $q^t$ is a square.
