摘要

已有文献表明，一般标量势的真空稳定性等价于其对应耦合张量的严格共容性。为了判断耦合张量的共占性，我们给出了严格共占张量的两个判据，并通过两个实例验证了\(\mathbb{Z}_{3}\)标量暗物质的一般标量势的真空稳定性，证明了它们的正确性和有效性。

Criteria of a Copositive Tensor with Application to Check Vacuum Stability of a General Scalar Potential

Existing literature shows that the vacuum stability of a general scalar potential is equivalent to the strict copositivity of its corresponding coupling tensor. In order to judge the copositivity of a coupling tensor, we provide two criteria of a strict copositive tensor, and show their correctness and effectiveness via two practical examples by checking the vacuum stability of a general scalar potential for \(\mathbb{Z}_{3}\) scalar dark matter.
