For example, a study in Heliyon [1] has delivered sharp bounds for the second and third Hankel determinants for starlike and convex functions associated with a three-leaf-shaped domain.

The field of functional analysis of symmetric analytic functions explores the interplay between the structure of analytic function algebras and the inherent symmetries dictated by invariance under ...

For Gaussian quadrature rules over a finite interval, applied to analytic or meromorphic functions, we develop error bounds from contour integral representations of the remainder term.

Human enterprise is increasingly affecting biodiversity beyond outright species losses, causing changes in ecosystem functions and the services they deliver to human beings. However, few tools are ...
