relatively prime

The problem of enumerating invertible cyclic matrices over any finite field with number of rows relatively prime to the characteristic of the field is solved

解决了任意有限域上行数与域特征互素的可逆循环矩阵的计数问题

We obtain there are only four behaviors of the trajectories near isolated critical points at the equator of the bounded cubic Kolmogorov type system , if the homogeneous polynomials of degree 3 are relatively prime .

证明了齐三次项互素时有界的三次Kolmogorov型系统在赤道上孤立奇点附近轨线的分布情况有且仅有4种。
