A New Advanced Class of Convex Functions with Related Results

open access: yesAxioms, 2023
It is the purpose of this paper to propose a novel class of convex functions associated with strong η-convexity. A relationship between the newly defined function and an earlier generalized class of convex functions is hereby established.

Approximately convex functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1952
So far we have discussed the stability of various functional equations. In the present section, we consider the stability of a well-known functional inequality, namely the inequality defining convex functions: $$f\left( {\lambda x + \left( {1 - \lambda } \right)y} \right) \leqslant \lambda f\left( x \right) + \left( {1 - \lambda } \right)f\left( y \

An application of the generalized Bessel function [PDF]

open access: yesMathematica Bohemica, 2017
We introduce and study some new subclasses of starlike, convex and close-to-convex functions defined by the generalized Bessel operator. Inclusion relations are established and integral operator in these subclasses is discussed.

New inequalities for F-convex functions pertaining generalized fractional integrals [PDF]

open access: yesMathematica Moravica, 2020
In this paper, the authors, utilizing F-convex functions which are defined by B. Samet, establish some new Hermite-Hadamard type inequalities via generalized fractional integrals.

Functions Like Convex Functions [PDF]

open access: yesJournal of Function Spaces, 2015
The paper deals with convex sets, functions satisfying the global convexity property, and positive linear functionals. Jensen's type inequalities can be obtained by using convex combinations with the common center. Following the idea of the common center, the functional forms of Jensen's inequality are considered in this paper.

DC Proximal Newton for Non-Convex Optimization Problems [PDF]

open access: yes, 2015
We introduce a novel algorithm for solving learning problems where both the loss function and the regularizer are non-convex but belong to the class of difference of convex (DC) functions.

Uniformly starlike functions and uniformly convex functions related to the Pascal distribution [PDF]

open access: yesMathematica Bohemica, 2021
In this article, we aim to find sufficient conditions for a convolution of analytic univalent functions and the Pascal distribution series to belong to the families of uniformly starlike functions and uniformly convex functions in the open unit disk ...

Robust Adaptive Beamforming for General-Rank Signal Model with Positive Semi-Definite Constraint via POTDC [PDF]

open access: yes, 2012
The robust adaptive beamforming (RAB) problem for general-rank signal model with an additional positive semi-definite constraint is considered. Using the principle of the worst-case performance optimization, such RAB problem leads to a difference-of ...

Root Function and Convex Function

open access: yesCommunications Faculty Of Science University of Ankara, 1974
Many authors [1], [2], [3], [4] considered the problems under different weak conditions which imply the continuity of the functions. In this section, we will consider convex functions on a commutative topological group with a root function.
