A new application of Schrödinger-type identity to singular boundary value problem for the Schrödinger equation

open access: yesBoundary Value Problems, 2019
In this paper, we present a modified Schrödinger-type identity related to the Schrödinger-type boundary value problem with mixed boundary conditions and spatial heterogeneities.

KUMMER’S THEOREM AND ITS CONTIGUOUS IDENTITIES [PDF]

open access: yesTaiwanese Journal of Mathematics, 2007
Recently Lavoie, Grondin and Rathie obtained ten results closely related to the classical Kummer's theorem as special cases from generalized Whipple's theorem on the sum of a ${}_3F_2$ with unit argument. The aim of this paper is to provide general summation formulas contiguous to the Kummer's theorem by simply using a known integral representation of

On the Carleman classes of vectors of a scalar type spectral operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
The Carleman classes of a scalar type spectral operator in a reflexive Banach space are characterized in terms of the operator's resolution of the identity. A theorem of the Paley-Wiener type is considered as an application.

Uniformly Primal Submodule over Noncommutative Ring

open access: yesJournal of Mathematics, 2020
Let R be an associative ring with identity and M be a unitary right R-module. A submodule N of M is called a uniformly primal submodule provided that the subset B of R is uniformly not right prime to N, if there exists an element s∈M−N with sRB⊆N.The set

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.

An identity theorem for logarithmic potentials

open access: yesOsaka Journal of Mathematics, 1991
The main result of the paper is the uniqueness theorem for superharmonic functions on the complex plane. Conditions of uniqueness are formulated in terms of their growth and their behaviour on a subset of the union of Riesz measures' supports, provided that this subset has finitely many connected components and its closure is the union of these ...

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

1/L 2 corrected soft photon theorem from a CFT3 Ward identity

open access: yesJournal of High Energy Physics, 2023
Classical soft theorems applied to probe scattering processes on AdS4 spacetimes predict the existence of perturbative 1/L 2 corrections to the soft photon and soft graviton factors of asymptotically flat spacetimes.

Fatou’s identity and Lebesgue’s convergence theorem [PDF]

open access: yesProceedings of the American Mathematical Society, 1999
The following two statements are typical results of the paper. Let \(P\) be a probability measure and \((f_n)\) a norm bounded sequence in the positive cone of \(L^1(P)\). (1) If \((f_n)\) converges in measure to \(f_\infty\), then \[ \liminf \int f_n dP= \min\{\eta(\{g_n: n\in\mathbb{N}\}): (g_n)\text{ is a subsequence of }(f_n)\}+ \int f_\infty dP. \]
