非奇异H-张量的新判定（英文）

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.
