摘要
引入了次完全非负矩阵的概念,建立了具有正对角元的次完全非负矩阵上的Hadamard不等式和Szasz不等式,推广了完全非负矩阵上的相关结论.
The concept of sub-totally nonnegative matrix is introduced,Hadamard’s inequality and Sza-sz’s inequality for sub-totally nonnegative matrices with positive entries are established,which generalize the relative conclusions for totally nonnegative matrices.
