On aNew Class of Meromorphically Univalent Functions with Applications to Geometric Functions [PDF]

open access: yesEngineering and Technology Journal, 2017
In this work, we inform a new class of meromorphic univalent function.We derive basic properties such ascoefficient estimates, convex set, extremepoints, radius of starlikeness and convexity, hadamard product, integraloperator,

An algebraic approach to the variants of convexity for soft expert approximate function with intuitionistic fuzzy setting

open access: yesJournal of Taibah University for Science, 2023
A new area of research called intuitionistic fuzzy soft expert set is expected to overcome the drawbacks of an intuitionistic fuzzy soft set in terms of eligibility for soft expert-argument approximate function.

Error Function and Certain Subclasses of Analytic Univalent Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
In the present investigation, our main aim is to introduce a certain subclass of analytic univalent functions related to the Error function. We discuss the implications of our main results, including the coefficient bound, extreme points, weighted mean ...

Point Cloud Repair Method via Convex Set Theory

open access: yesApplied Sciences, 2023
The point cloud is the basis for 3D object surface reconstruction. An incomplete point cloud significantly reduces the accuracy of downstream work such as 3D object reconstruction and recognition.

Covering graphs with convex sets and partitioning graphs into convex sets [PDF]

open access: yesInformation Processing Letters, 2020
We present some complexity results concerning the problems of covering a graph with $p$ convex sets and of partitioning a graph into $p$ convex sets. The following convexities are considered: digital convexity, monophonic convexity, $P_3$-convexity, and $P_3^*$-convexity.

Quasi Semi and Pseudo Semi (p,E)-Convexity in Non-Linear Optimization Programming

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The class of quasi semi -convex functions and pseudo semi -convex functions are presented in this paper by combining the class of -convex functions with the class of quasi semi -convex functions and pseudo semi -convex functions, respectively.

Convex Analysis for Minimizing and Learning Submodular Set Functions [PDF]

open access: yes, 2013
The connections between convexity and submodularity are explored, for purposes of minimizing and learning submodular set functions. First, we develop a novel method for minimizing a particular class of submodular functions, which can be expressed as a

On a Class of Generalized Nonexpansive Mappings

open access: yesMathematics, 2020
In our recent work we have introduced and studied a notion of a generalized nonexpansive mapping. In the definition of this notion the norm has been replaced by a general function satisfying certain conditions.

On Sumsets of Convex Sets

open access: yesCombinatorics, Probability and Computing, 2011
A set of reals A = {a1,. . .,an} is called convex if ai+1 − ai > ai − ai−1 for all i. We prove, among other results, that for some c > 0 every convex A satisfies |A−A| ≥ c|A|8/5log−2/5|A|.
