A trace inequality for positive definite matrices
E. V. Belmega, S. Lasaulce, M. Debbah
In this note we prove that Tr (MN+ PQ)>= 0 when the following two conditions are met: (i) the matrices M, N, P, Q are structured as follows: M = A -B, N = inv(B)-inv(A), P = C-D, Q…

A generalization of a trace inequality for positive definite matrices
E. V. Belmega, M. Jungers, S. Lasaulce
In this note we generalize the trace inequality derived by [1] to the case where the number of terms of the sum (denoted by K) is arbitrary.
