Abstract: In matrix theory and numerical analysis there are two very famous and important results. One is Geršgorin circle theorem, the other is strictly diagonally dominant theorem. They have important application and research value, and have been widely used and studied. In this paper, we investigate generalized diagonally dominant matrices and matrix eigenvalue inclusion regions. A class of G-function pairs is proposed, which extends the concept of G-functions. Thirteen kind of G-function pairs are established. Their… Show more
