The Improvement of the Lower Bound of the Matrix Product Determinant
【摘要】 李耀堂和李继成眼JournalofComputationalMathematics熏19穴4雪穴2001雪365-370演给出两个H-矩阵乘积的行列式的下界估计,应用我们所得的M-矩阵的Hadamard乘积的Oppenheim型不等式的新结论和方法,推广和改进了李耀堂和李继成的相应结论。
【Abstract】 Li Yao-tang and Li Ji-cheng have estimated the lower bounds of two H-matrix product determinants recently. With the application of the new conclusion and method we obtained from the Oppenheim inequation of M-matrix Hadamard Product, we have generalized and improved Li Yao-tang and Li Ji-cheng’s corresponding conclusion.
