Recent progress in random metric theory and its applications to conditional risk measures

open access: yes, 2011
The purpose of this paper is to give a selective survey on recent progress in random metric theory and its applications to conditional risk measures. This paper includes eight sections. Section 1 is a longer introduction, which gives a brief introduction

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics

open access: yesAdvanced Functional Materials, EarlyView.
Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

On the Exact Solution for the Schrödinger Equation

open access: yesParticles
For almost 75 years, the general solution for the Schrödinger equation was assumed to be generated by an exponential or a time-ordered exponential known as the Dyson series.

Strongly λ-convergence of order α in Neutrosophic Normed Spaces

open access: yesDera Natung Government College Research Journal, 2022
In this paper, we introduce the concept of strongly \lambdaλ-convergence of order \alphaα in the neutrosophic normed spaces. We investigate some fundamental properties of this new concept.

The Khinchin-Kahane and Levy inequalities for abelian metric groups, and transfer from normed (abelian semi)groups to Banach spaces

open access: yes, 2023
The Khinchin-Kahane inequality is a fundamental result in the probability literature, with the most general version to date holding in Banach spaces. Motivated by modern settings and applications, we generalize this inequality to arbitrary metric groups ...

Hydrogen‐Bond–Driven Ion Retention in Electrolyte‐Gated Synaptic Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Anion molecular design governs ion–polymer interactions in electrolyte‐gated synaptic transistors. Asymmetric anions induce hydrogen‐bond interactions that suppress ion back‐diffusion and stabilize doping, enabling enhanced nonvolatile synaptic properties.

On Spaces with Norms of Negative and Positive Order [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
The two Hilbert spaces H 0 {H_0} and H 1 {H_1} are defined to be a generating pair if H 1 {H_1} is a dense subspace of H 0 {H_0} and if ...
