Power majorization between the roots of two polynomials

Minghua Lin, Gord Sinnamon

It is shown that if two hyperbolic polynomials have a particular factorization into quadratics, then their roots satisfy a power majorization relation whenever key coefficients in…

New properties for certain positive semidefinite matrices

Minghua Lin

We bring in some new notions associated with $2 \times 2$ block positive semidefinite matrices. These notions concern the inequalities between the singular values of the off diagona…

On a determinantal inequality arising from diffusion tensor imaging

Minghua Lin

In comparing geodesics induced by different metrics, Audenaert formulated the following determinantal inequality $det (A^{2} + ∣ B A ∣) \leq det (A^{2} + A B),$ where $A, B$ are $n \times n$ po…

On Drury's solution of Bhatia \& Kittaneh's question

Minghua Lin

Let $A, B$ be $n \times n$ positive semidefinite matrices. Bhatia and Kittaneh asked whether it is true $σ_{j} (A B) \leq \frac{1}{2} λ_{j} (A + B), j = 1, \dots, n$ where $σ_j…
