乘法群 meaning in English

multiplicative group

The second approach is to use the concept of discrete logarithm . understanding this concept requires understanding some properties of multiplicative groups
第二种方法就是运用离散对数的概念。要掌握这些概念首先需要了解乘法群的概念。
And for geometrically split link , sharp integrality of the ohtsuki invariant is given . a new multiplicative group , braid array , is constructed through a series of basic changes in the second part , and we conclude that any tame knot or link can be represented by finite braid array
第二部分，由于辫子群与纽结理论的密切联系，本文构造了一个类似于矩阵的乘法群? ?辫子阵群，并给出了它的一系列基本变换，且得到所有温良纽结或环链都可由有限阶辫子阵惟一表示。
The primary advantage that elliptic curve systems have over systems based on the multiplicative group of a finite field ( and also over systems based on the intractability of integer factorization ) is the absence of a subexponential - time algorithm ( such as those of index calculus type ) that could find discrete logs in these groups
与基于有限域的乘法群系统(及基于整数分解的难解性之上的系统)相比,椭圆曲线系统的优势在于,迄今为止还没找到这类群上离散对数的次指数时间算法(如微积分类)
