- 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
本文分为三个部分,主要研究了线性互补问题的几个相关的公开问题以及猜想: ( 1 )研究了murthy等在[ 2 ]中提出的公开问题,即对任意的矩阵a ,其扩充矩阵是否为q _ 0 -矩阵,给出了肯定的回答,得到充分矩阵的扩充矩阵是充分矩阵,并讨论了graves算法,证明了若a是双对称的p _ 0 -矩阵时, lcp ( q , a )可由graves算法给出; ( 2 )研究了murthy等在[ 6 ]中提出关于半正定矩阵的猜想,给出了半正定矩阵的一些充分条件,并研究了pang ~ -猜想,得到了只r _ 0 -矩阵与q -矩阵的二个等价条件,以及e _ 0 q -矩阵的一些性质; ( 3 )研究了danao在[ 25 ]中提出的danao猜想,即,若a为p _ 0 -矩阵,则,我们给出了反例证明了此猜想当n 4时不成立,指出了murthy等在[ 20 ]中的一些错误,得到n = 2 , 3时,即[ 25 ]中定理3 . 2中a p _ 0的条件可以去掉。
