A Set of Subdividing and Iterative Criteria for Nonsingular H-matrices

Nonsingular H-matrices play a very important role in matrix theory,economical mathematics,physics and power system theory,etc.In this paper,through selecting coeffcient progressively and dividing region recursively,we obtain a set of subdividing and iterative criteria for nonsingular H-matrices,which extend and improve some related results.Advantages are illustrated by numerical examples.
