A linear map between real symmetric matrix spaces is positive if all positive semidef-inite matrices are mapped to positive semidefinite ones. A real symmetric matrix is sep-arable if it can be written as a summation of Kronecker products of positive semidefinite matrices. This paper studies how to check if a linear map is positive or not and how to check if a matrix is separable or not.
