Abstract

H -tensor plays an important role in identifying positive definiteness of even order real symmetric tensors. In this paper, some definitions and theorems related to H -tensors are introduced firstly. Secondly, some new criteria for identifying nonsingular H -tensors are proposed, moreover, a new theorem for identifying positive definiteness of even order real symmetric tensors is obtained. Finally, some numerical examples are given to illustrate our results.

Key words： H-tensors; Generalized diagonally dominant; M-tensors
