Radius of convergence of a power series [PDF]

open access: yesInternational Journal of Mathematical Education in Science and Technology, 2003
We derive two simple and memorizable formulas for the radius of convergence of a power series which seem to be appropriate for teaching in an introductory calculus course.

Some Inequalities for the Euclidean Operator Radius of Two Operators in Hilbert Spaces [PDF]

open access: yes, 2006
Some sharp bounds for the Euclidean operator radius of two bounded linear operators in Hilbert spaces are given. Their connection with Kittaneh’s recent results which provide sharp upper and lower bounds for the numerical radius of linear operators ...

Norm and Numerical Radius Inequalities for a Product of Two Linear Operators in Hilbert Spaces [PDF]

open access: yes, 2006
The main aim of the present paper is to establish some norm and numerical radius inequalities for the composite operator BA under suitable assumptions for the transform Cα ,β (T) := (T∗ −α I)(β I−T) , where α ,β ∈ C and T ∈ B(H), of the operators ...

Quasinormal modes in charged fluids at complex momentum

open access: yesJournal of High Energy Physics, 2020
We investigate the convergence of relativistic hydrodynamics in charged fluids, within the framework of holography. On the one hand, we consider the analyticity properties of the dispersion relations of the hydrodynamic modes on the complex frequency and

Increasing the order of convergence of multistep methods for solving systems of equations under weak conditions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2019
In the present paper, we consider a construction proposed in Xiao and Yin (2016) to improve the order of convergence of the method from p to p + 2m under weaker assumptions.

High temperature expansion of double scaled SYK

open access: yesPhysics Letters B, 2023
We study the high temperature (or small inverse temperature β) expansion of the free energy of double scaled SYK model. We find that this expansion is a convergent series with a finite radius of convergence. It turns out that the radius of convergence is
