一类矩阵中负元素的个数
摘要
元素全是非正实数的矩阵A称为负矩阵.文中利用低阶负矩阵的研究结果考虑了一类四阶负矩阵中负元素的个数
同时论证了该矩阵在一些附加条件下负元素的个数最多为10.
Abstract
A negative matrix refers to the matrix in which all the elements are either negative or zero.By virtue of the research products on low-order negative matrixes
this paper has made a research on the number of negative elements in a category of order-four negative matrixes
and has proved that
under certain additional conditions
the maximum number of negative element of such matrixes is 10.
