摘要：
The class of strictly gamma-diagonally dominant matrices is an important subclass of the nonsingular H-matrices. In this paper, by use of the properties of Schur complements, we present lower and upper bounds for determinants of strictly gamma-diagonally dominant matrices. Moreover, these bounds may improve the corresponding results for the strictly diagonally dominant matrices. The effectiveness and superiority of the obtained bounds are demonstrated through several numerical examples.
