Convexity and concavity theorems on positive matrices and applications to geometric means and Khatri-rao products by Kilicman, Adem, Al Zhour, Zeyad Abdel Al Ziz

“…We apply the concavity and convexity theorems in order to obtain new unusual estimates for the Khatri-Rao product positive definite matrices. Finally, the results lead inequalities involving Hadamard product and Ando’s (α − power) geometric mean, as a special case. …”
