Another determinantal inequality involving partial traces

Yongtao Li, Lihua Feng, Weijun Liu +1

Let $A$ be a positive semidefinite $m \times m$ block matrix with each block $n$ -square, then the following determinantal inequality for partial traces holds \[ (\mathrm{tr} A)^{mn}…

A new matrix inequality involving partial traces

Yongtao Li, Weijun Liu, Yang Huang

Let $A$ be an $m \times m$ positive semidefinite block matrix with each block being $n$ -square. We write $tr_{1}$ and $tr_{2}$ for the first and second partial trace,…

Some applications of two completely copositive maps

Yongtao Li, Yang Huang, Lihua Feng +1

A linear map $Φ : M_{n} \to M_{k}$ is called completely copositive if the resulting matrix $[Φ (A_{j, i})]_{i, j = 1}^{m}$ is positive semidefinite for any integer $m$ and pos…
