| Abstract: | This paper mainly discussed the pointwise degeneracy of linear delay differential equations.With the knowledge of matrix,we give the necessary and sufficient conditions of pointwise degeneracy on n-order delay differential equations.In addition,we also obtain the algebraic criteria of pointwise degeneracy for n-order linear delay differential equations.We think that it will widen the field of this system. |
