In this thesis, we study some open problems and conjectures about the linear complementarity problem. 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. the condition of theorem 3. 2 of [ 25 ] that a p0 can be deleted and obtain a e " a is an almost e - matrix if a is a co - matrix or column sufficient matrix
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,即對任意的矩陣a ,其擴充矩陣是否為q _ 0 -矩陣,
給出了肯定的回答,得到充分矩陣的擴充矩陣是充分矩陣,並討論了graves演算法,證明了若a是雙對稱的p _ 0 -矩陣時, lcp ( q , a )可由graves演算法
給出; ( 2 )研究了murthy等在[ 6 ]中提
出關於半正定矩陣的猜想,
給出了半正定矩陣的一些充分條件,並研究了pang ~ -猜想,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; ( 3 )研究了danao在[ 25 ]中提
出的danao猜想,即,若a為p _ 0 -矩陣,則,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,得到n = 2 , 3時,即[ 25 ]中定理3 . 2中a p _ 0的條件可以去掉。
This thesis firstly introduces new demands of aerial product logistics support under high - tech war and some defects of traditional logistics support, and puts forward a kind of system model of aerial product logistics support following data - sharing of cals, and emphasizes detm. secondly it sets forth application of step and xml in the ietm, researchs conversion of xml schema and relation schema, and simply researchs mapping of xml and express. afterword, a based - xml framework of info - transfer between different platform are presented, according to this framework, the author establish a archetypal system of helicopter information query system based xml and dbms
