Weak block diagonally dominant matrices, weak block H-matrix and their applications 1
Linear Algebra and its Applications 282(1998)263-274,-0001,():
Here we introduce more general definitions of weak block diagonally dominant ma-trix and weak block H-matrix which permit block triangular factorizations and extend the theory to the block diagonally dominant matrices and the block H-matrices. Fur-thermore,by the theory of weak block H-matrix, we prove that any partitioned block form of a pointwise H-matrix has a block triangular factorization. 1998 Elsevier Science Inc.
