A Note On Convexity Inequalities Of Weighted Matrix Geometric Means

Victoria M Chayes

We offer a new proof of uniform convexity inequalities for the Finsler manifold of nonpositive curvature taken on the space of positive-semidefinite matrices with the weighted matr…

Hanner's Inequality For Positive Semidefinite Matrices

Victoria M. Chayes

We prove an analogous Hanner's Inequality of $L^{p}$ spaces for positive semidefinite matrices. Let $∣∣ X ∣ ∣_{p} = Tr [(X^{*} X)^{p /2}]^{1/ p}$ denote the $p$ -Schatten norm of a matr…

Reverse Holder, Minkowski, And Hanner Inequalities For Matrices

Victoria Chayes

We examine a number of known inequalities for $L^{p}$ functions with reverse representations for $s < 1$ with complex matrices under the $p$ -norms $||X||_p=\text{Tr}[(X^\ast X)^{p/2}]^…

Matrix Rearrangement Inequalities Revisited

Victoria M Chayes

Let $∣∣ X ∣ ∣_{p} = Tr [(X^{*} X)^{p /2}]^{1/ p}$ denote the $p$ -Schatten norm of a matrix $X \in M_{n \times n} (C)$ , and $σ (X)$ the singular values with $↑$ $\downarro…
