In Chapter 5, we study how the co-primeness of element orders of a finite group influences its structure.
第五章主要研究有限群中元素的阶的互素性对群结构的影响。
Finite automaton, a computational model of extremely limited computing ability, was proved to have the capability of solving primeness test by construction.
有穷自动机,一种计算能力极其有限的计算模型,具有解决素性测试的能力通过构造法得到了证明。
You can't tell for certain that a number is prime without trying to factor it, but you can apply a number of simpler tests that will verify its primeness to any degree of certainty that you want.
