WebIn order to figure out what range the eigenvalues of a certain matrix would be in we can use Gershgorin’s Theorem. 1 Strictly Diagonally Dominant Matrices Before we get to Gershgorin’s Theorem it is convenient to introduce a condition for matrices known as Strictly Diagonally Dominant. While Gershgorin’s Theorem can be WebIn this paper, we study two classes of quasi-double diagonally dominant tensors and prove they are H-tensors. Numerical examples show that two classes of H-tensors are mutually exclusive. Thus, we extend the decision conditions of H-tensors. Based on these two classes of tensors, two estimation inequalities for the upper and lower bounds for the …
