Improved eigenvalue inequalities via two major subclasses of superquadratic functions

Mohsen Kian

There exist two major subclasses in the class of superquadratic functions, one comprises concave and decreasing functions, while the other consists of convex and monotone increasin…

Matrix Inequalities between $f (A) σ f (B)$ and $A σ B$

Manisha Devi, Jaspal Singh Aujla, Mohsen Kian +1

Let $A$ and $B$ be $n \times n$ positive definite complex matrices, let $σ$ be a matrix mean, and let $f : [0, \infty) \to [0, \infty)$ be a differentiable convex function with $f(0)=…
