Preservation of Extreme Points

open access: yesMathematics, 2022
We characterize the extreme points of the closed unit ball of the dual of a Banach space which are preserved by the adjoint of any extreme operator. The result is related to the structure topology introduced by Alfsen and Effros on the set of all extreme

Sufficient Statistics and Extreme Points

open access: yesAnnals of Probability, 1978
A convex set $M$ is called a simplex if there exists a subset $M_e$ of $M$ such that every $P \in M$ is the barycentre of one and only one probability measure $\mu$ concentrated on $M_e$. Elements of $M_e$ are called extreme points of $M$. To prove that a set of functions or measures is a simplex, usually the Choquet theorem on extreme points of convex

A Generalized Class of Univalent Harmonic Functions Associated with a Multiplier Transformation [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2021
We define a new subclass of univalent harmonic mappings using multiplier transformation and investigate various properties like necessary and sufficient conditions, extreme points, starlikeness,  radius of convexity.

Objects as Extreme Points [PDF]

open access: yes, 2021
Object detection can be regarded as a pixel clustering task, and its boundary is determined by four extreme points (leftmost, top, rightmost, and bottom). However, most studies focus on the center or corner points of the object, which are actually conditional results of the extreme points.

Extreme points of the Besicovitch-Orlicz space of almost periodic functions equipped with Orlicz norm [PDF]

open access: yesOpuscula Mathematica, 2021
In the present paper, we give criteria for the existence of extreme points of the Besicovitch-Orlicz space of almost periodic functions equipped with Orlicz norm.

Meromorphic functions with missing coefficients defined by $q$-derivative [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
By considering a fixed point in the punctured unit disk and using the $q$--derivative, a new subfamily of meromorphic and univalent functions is defined.

On Geometric Properties of a Certain Analytic Function with Negative Coefficients

open access: yesFractal and Fractional, 2022
Various function theorists have successfully defined and investigated different kinds of analytic functions. The applications of such functions have played significant roles in geometry function theory as a field of complex analysis.

The relationship between the number of extrema of compound sinusoidal signals and its high-frequency component [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
As the main findings of our research work, we present a novel theorem on the relationship between the number of extrema of compound sinusoidal signals and its high-frequency component.

Extreme Points in Orlicz Spaces Equipped with Snorm

open access: yesJournal of Harbin University of Science and Technology, 2020
The extreme points and strongly extreme points are important contents of Banach space. In order to study the extreme points of Orlicz space equipped with snorm, some basic properties of the snorm are discussed firstly.

Quantum circuit simulation of superchannels

open access: yesNew Journal of Physics, 2023
Quantum simulation is one of the central discipline to demonstrate the power of quantum computing. In recent years, the theoretical framework of quantum superchannels has been developed and applied widely as the extension of quantum channels.
