A LITTLE“NEW BOUNDS”OF EIGENVALUEABOUT NEW TYPE “COMBINATORIAL MATRIXS”

定义了一种新型多元“组合矩阵” ,通过对该矩阵的范数、谱半径与特征值的“新界”论证 ,提供了估算‖A-1‖ ∞ 、‖M-1 N‖ ∞上界、ρ(M -1 N)、λ(M-1 N)与λi(A +B)

In this paper a species of new type polybasic“Combinatorial Matrixs”are defined.By proving“New Bounds”of model number and spectral radius and eigenvalue of this matrix,the estimative formulas of upper bounds for ‖A -1 ‖ ∞、‖M -1 N‖ ∞,upper lower bounds for ρ(M -1 N),λ(M -1 N)、λ i(A+B)are presented.The examples of demonstration are also given.
