论文摘要
本手稿的目的是了解真实对称矩阵$ \ MATHCAL {s}^n $的结构，它使不变的封闭凸锥的共呈态和完全正面的矩阵（$ cop_n $和$ cp_n $）。 $ \ Mathcal {s}^2 $上的可逆线性映射的描述，以便完全确定$ l（cp_2）\ subset cp_2 $。
The objective of this manuscript is to understand the structure of an invertible linear map on the space of real symmetric matrices $\mathcal{S}^n$ that leaves invariant the closed convex cones of copositive and completely positive matrices ($COP_n$ and $CP_n$). A description of an invertible linear map on $\mathcal{S}^2$ such that $L(CP_2) \subset CP_2$ is completely determined.
