A Voronovskaya-type theorem for a positive linear operator

International Journal of Mathematics and Mathematical Sciences, 2006
We consider a sequence of positive linear operators which approximates continuous functions having exponential growth at infinity.

Sector operator inequalities involving positive linear maps

Journal of Inequalities and Applications
In this note, we prove the pth power ( p ≥ 2 $p\geq 2$ ) of two new sector operator inequalities for positive linear maps which are due to Bedrani et al. (Positivity 25:1601-1629, 2021) and Nasiri (Filomat 38:3429-3438, 2024), respectively.

A Linear Composition Operator on the Bloch Space

Mathematics
Let n∈N0, ψ be an analytic self-map on D and u be an analytic function on D. The single operator Du,ψn acting on various spaces of analytic functions has been a subject of investigation for many years.

On a nonlinear spectral problem

Современная математика: Фундаментальные направления
The problem of perturbation of the spectrum of a linear operator by a linear operator is solved thanks to the introduced concepts of holomorphic families of operators of type (A) and in the sense of Kato.

Asymptotically Newton-Type Methods without Inverses for Solving Equations

Mathematics
The implementation of Newton’s method for solving nonlinear equations in abstract domains requires the inversion of a linear operator at each step. Such an inversion may be computationally very expensive or impossible to find.
