“…where C σ X ,σ Y depends only on σ X and σ Y . Up to this constant, this is precisely the main result of [6]. In fact, our method can reproduce their exact result, which we present as a warm up in the next section.…”

“…For any given continuous density f over R 2 , there exists a differentiable transformation T : R 2 → R 2 with symmetric positive definite Jacobian T ′ (noted T ′ > 0) such that X = T ( X * ) has density f . Courtade et al [18] noted that the Brenier map can be used in the transportation proof of [5] to prove Shannon's vector EPI. We find it also convenient to prove the complex matrix EPI: Theorem 2: The matrix EPI (3) holds for any m × n complex matrix A and any random vector X of independent complex components X i , where X * is a c-normal vector with independent components X * i satisfying (4).…”
