Positive semi-definite matrices, exponential convexity for multiplicative majorization and related means of Cauchy's type
In this paper, we obtain new results concerning the generalizations of additive and multiplicative majorizations by means of exponential convexity. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type results which implies exponential convexity an...
