Positive Semidefinite Matrices, Exponential Convexity for Majorization, and Related Cauchy Means
<p/> <p>We prove positive semidefiniteness of matrices generated by differences deduced from majorization-type results which implies exponential convexity and log-convexity of these differences and also obtain Lyapunov's and Dresher's inequalities for these differences. We intr...
