zero matrix

Based on theories of multi-objective decision making and fuzzy game, the multi-objective two-person zero-sum matrix game, whose payoff value is a vague value is studied.

根据多目标决策和模糊对策理论，研究支付值为Vague值的多目标二人零和矩阵对策。

Two solution methods regarding vague multi-objective two-person zero-sum matrix game are discussed: one is making the vague multi-objective game problem certain through the order function of vague values first, then turning it into single objective game;

讨论了Vague多目标二人零和矩阵对策的两种求解方法：一是先将Vague多目标对策问题清晰化，再转化为单目标对策问题求解；

A special two-person zero-sum finite game, in which every player has a warning level of the gain and loss, is posed. It is said to be the Matrix B-Game.

提出了一类局中人都设定有得失控制值的二人零和有限对策，即B矩阵对策。

If a matrix game is isomorphic to a matrix game with zero game value, then the latter is called annihilation of the former.

如果矩阵对策同构于一个对策值为零的矩阵对策，那么后者称为前者的零化。

This paper prores the complex singular square matrix T which is tux power zero matrices product A and B, moreover matrices A, band T hare the same rank except 22 rank I power zero matrix T.

证明了复奇异方阵T是两个幂零矩阵A和B的乘积，且除T是一个秩为1的2×2阶幂零矩阵外有A、B、T的秩相同。

The coefficient matrix of the linear equations is nonpositive definite because of the restrictions, but we prove the leading principal minors of the matrix do not equal zero and the triangular decomposition or Gaussian elimination can be used to the linear equations.

由于约束条件的缘故，导出的线性方程组的系数矩阵不是正定的，但本文证明了它的各阶顺序主子式不等于零，从而可用三角分解法或高斯消去法。

It is common knowledge that a zero sum two-person finite game is also called matrix game.

众所周知，零和二人有限对策也称为矩阵对策。

A square sign pattern matrix that does not have a zero row or zero column is sign potentially orthogonal ( SPO) if every pair of rows and every pair of columns allow orthogonality.

一个没有零行或零列的n阶符号模式矩阵是符号蕴含正交的，若每一对行和列向量都是蕴含正交的。
