Criterion for Positive Definiteness of Real Symmetric Tensors
摘要
Abstract
We gave a new criterion for H-tensors by constructing different positive diagonal matrices combined with scaling techniques of inequalities,and gave new practical criteria conditions for the positive definiteness of an even-order real symmetric tensor,i.e.,an even-degree homogeneous polynomials.关键词
