RDDE点态退化的充要条件

The complece and necessary conditions of the pointwise degeneracy RDDE

借助于矩阵有关知识 ,给出了n维差分微分方程可验证的点态退化的充要条件。n =2时 。

With the knowledge of matrix, we give the complete and necessary conditions of n-dimensional differential-difference equation. When n=2, we have the related results for multi-delayed R-type and N-type.
