中文摘要：
本文研究了双随机循环矩阵中素元的分类问题．由于任一n阶双随机循环矩阵都可以唯一地表示为移位的n-1次一元多项式,从而可把双随机循环矩阵中素元的分类问题简化为解双随机循环矩阵上的一个方程．应用此原理,本文完全解决了判别具有位数3的n阶双随机循环矩阵是否为素元的问题,并给出了n阶双随机循环矩阵中一类具有位数4的素元．
英文摘要：
The classification of primes in the doubly stochastic circulant matrices is now explored. Since any n x n doubly stochastic circulant matrix has a unique representation as a polynomial of degree n - 1 in the shift operator wn, the classification problem of primes in the doubly stochastic circulant matrices can be reduced to the solution of an equation over a doubly stochastic circulant matrix. By this means, the problem of deciding whether an n x n doubly stochastic circulant matrix A of order 3 is a prime is completely solved. A class of primes in the n × n doubly stochastic circulant matrices of order 4 is also presented.
