Notes on certain p-valent functions [PDF]

open access: yesGeneral Mathematics, 2019
Abstract Let Ap be the class of functions f(z) which are analytic in the open unit disk U. Applying some subordinations for functions, some interesting properties for f(z) ∈Ap are showed. Our results are generalizations for results given before.

a*-families of analytic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Using convolutions, a new family of analytic functions is introduced. This family, called a*-family, serves in certain situations to unify the study of many previously well known classes of analytic functions like multivalent convex, starlike, close-to ...

Subclasses of p-Valent Functions Associated with Linear q-Differential Borel Operator

open access: yesMathematics, 2023
The aim of the present paper is to introduce and study some new subclasses of p-valent functions by making use of a linear q-differential Borel operator.We also deduce some properties, such as inclusion relationships of the newly introduced classes and ...

Differential sandwich theorems of p−valent analytic functions involving a linear operator

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this paper we derive some subordination and superordination results for certain p-valent analytic functions in the open unit disc, which are acted upon by a class of a linear operator.

Classification of affine homogeneous spaces of complexity one

open access: yes, 2004
The complexity of an action of a reductive algebraic group G on an algebraic variety X is the codimension of a generic B-orbit in X, where B is a Borel subgroup of G. We classify affine homogeneous spaces G/H of complexity one.

Notes on p-valently Bazilević functions

open access: yesApplied Mathematics Letters, 1991
Let \({\mathcal A}_ p\) be the family of functions f of the form \(f(z)=z^ p+a_{p+1}z^{p+1}+...\), (p\(\in \{1,2,...\})\), that are analytic in the unit disc \(\Delta =\{z:| z| \beta,\quad z\in \Delta \}, \] \[ {\mathcal C}_ p(\alpha,\beta)=\{f\in {\mathcal A}_ p:\;Re J(f(z);\alpha)0\), \(0\leq -\beta /\alpha \leq 1/2\) (or \(f\in {\mathcal C}_ p ...

Electroactive Metal–Organic Frameworks for Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Spectral problem on graphs and L-functions

open access: yes, 1999
The scattering process on multiloop infinite p+1-valent graphs (generalized trees) is studied. These graphs are discrete spaces being quotients of the uniform tree over free acting discrete subgroups of the projective group $PGL(2, {\bf Q}_p)$.
