摘要
研究了非奇异块H-矩阵的判定问题,利用广义块α1-严格对角占优矩阵的定义,块α1-严格对角占优定理,使用反证法和构造性证明法,得到了非奇异块H-矩阵新的判据。
The paper studies the judgment problem of nonsingular blockH-matrices and obtains new criteria of nonsingular blockH-matrices by using the deifnition of generalized block strict-diagonal-dominant matrices, block strict-diagonal-dominant theorem and the methods of the reduction to absurdity and the construction veriifcation.
