Abstract

Strong ℋ-tensors play an important role in identifying positive semidefiniteness of even-order real symmetric tensors. We provide several simple practical criteria for identifying strong ℋ-tensors. These criteria only depend on the elements of the tensors; therefore, they are easy to be verified. Meanwhile, a sufficient and necessary condition of strong ℋ-tensors is obtained. We also propose an algorithm for identifying the strong ℋ-tensors based on these criterions. Some numerical results show the feasibility and effectiveness of the algorithm.
