An ℋ-tensor-based criteria for testing the positive definiteness of multivariate homogeneous forms
A positive definite homogeneous multivariate form plays an important role in the field of optimization, and positive definiteness of the form can be identified by a special structured tensor. In this paper, based on the equivalence between the form and the corresponding tensor, and the links of the...
