Using the main result, we also obtain a simple criterion to check if a given C(superscript *)-algebra A is Abelian, that is, A is Abelian if and only for any two positive elements a, b∈A, there is a'∈A such that ab=ba'.

利用文中的主要結(jié)論，還得到了判斷C-代數(shù)A是交換一個簡單條件亚洲综合色色，即A是交換的當且僅當對A中的任何兩個正元a狼友视频新网址，b存在a'∈A使得ab=ba'。

It consists of the next three aspects: firstly, we study Murthys' open problem whether the augmented matrix is a Q0-matrix for an arbitary square matrix A , provide an affirmable answer to this problem , obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the Graves algorithm can be used to solve linear complementarity problem with bisymmetry Po-matrices; Secondly, we study Murthys' conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study Pang's conjecture , obtain two conditions when R0-matrices and Q-matrices are equivelent and some properties about E0 ∩ Q-matrices; Lastly, we give a counterexample to prove Danao's conjecture that if A is a Po-matrix, A ∈ E' A ∈ P1* is false, point out some mistakes of Murthys in [20] , obtain when n = 2 or 3, A ∈ E' A ∈ P1*, i.e.

本文分為三個部分，主要研究了線性互補問題的幾個相關的公開問題以及猜想：(1)研究了Murthy等在[2]中提出的公開問題性爱视频喷水，即對任意的矩陣A官方网站夫妻一级黄色录像片子，其擴充矩陣是否為Q_0-矩陣，給出了肯定的回答嗯啊～嗯啊使劲视频在线观看，得到充分矩陣的擴充矩陣是充分矩陣日本最新黄色視頻夜夜操，并討論了Graves算法，證明了若A是雙對稱的P_0-矩陣時九九久久精品无码专区，LCP可由Graves算法給出色哟哟网址；(2)研究了Murthy等在[6]中提出關于半正定矩陣的猜想，給出了半正定矩陣的一些充分條件在线国产精品，并研究了Pang~-猜想男女无遮挡猛进猛出动态图，得到了只R_0-矩陣與Q-矩陣的二個等價條件，以及E_0∩Q-矩陣的一些性質(zhì)人人操,人人看,人人叉；(3)研究了Danao在[25]中提出的Danao猜想男人天堂网免费视频在线，即，若A為P_0-矩陣欧美熟女乱交，則手机在线一区二区，我們給出了反例證明了此猜想當n≥4時不成立，指出了Murthy等在[20]中的一些錯誤最新免费黄网，得到n=297综合干视频，3時，即[25]中定理3.2中A∈P_0的條件可以去掉在线看日本片专区品尚网。
