A Physics‐Informed Learning Framework to Solve the Infinite‐Horizon Optimal Control Problem

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT We propose a physics‐informed neural networks (PINNs) framework to solve the infinite‐horizon optimal control problem of nonlinear systems. In particular, since PINNs are generally able to solve a class of partial differential equations (PDEs), they can be employed to learn the value function of the infinite‐horizon optimal control problem via

Portfolio Optimization for Pension Purposes: Literature Review

Journal of Economic Surveys, EarlyView.
ABSTRACT This systematic review identifies persistent challenges and gaps in the literature on pension portfolio optimization models. We searched, selected, and critically analyzed 82 articles from three major academic databases published over the past decade to investigate the barriers to the effective implementation of these models.

Symmetry algebra for the generic superintegrable system on the sphere

Journal of High Energy Physics, 2018
The goal of the present paper is to provide a detailed study of irreducible representations of the algebra generated by the symmetries of the generic quantum superintegrable system on the d-sphere.

On classical solutions and canonical transformations for Hamilton–Jacobi–Bellman equations

Bulletin of the London Mathematical Society, Volume 57, Issue 7, Page 2045-2057, July 2025.
Abstract In this note, we show how canonical transformations reveal hidden convexity properties for deterministic optimal control problems, which in turn result in global existence of Cloc1,1$C^{1,1}_{loc}$ solutions to first‐order Hamilton–Jacobi–Bellman equations.

Stimulated Raman Scattering with Optical Vortex Beams

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.

Jacobi-weighted orthogonal polynomials on triangular domains

Journal of Applied Mathematics, 2005
We construct Jacobi-weighted orthogonal polynomials 𝒫n,r(α,β,γ)(u,v,w),α,β,γ>−1,α+β+γ=0, on the triangular domain T. We show that these polynomials 𝒫n,r(α,β,γ)(u,v,w) over the triangular domain T satisfy the following properties: 𝒫n,r(α,β,γ)(u,v,w)∈ℒn,n ...

Extended Jacobi polynomials [PDF]

International Journal of Contemporary Mathematical Sciences, 2014
In this paper, with the help of generalized hypergeometric functions of the type 4 2 F , an extension of the Jacobi polynomials is established and a number of generating functions similar to those of classical Jacobi polynomials have been proved.

The role of target populations in resident support for local collaboration

Public Administration Review, Volume 85, Issue 4, Page 1115-1133, July/August 2025.
Abstract The characteristics of populations benefiting from collaboration are mostly regarded as contextual factors in collaborative theory and research. Drawing on policy design and distributive justice theories, this study seeks to understand how public support for collaboration varies depending on the characteristics of the target population that ...

Collocation Method via Jacobi Polynomials for Solving Nonlinear Ordinary Differential Equations

International Journal of Mathematics and Mathematical Sciences, 2011
We extend a collocation method for solving a nonlinear ordinary differential equation (ODE) via Jacobi polynomials. To date, researchers usually use Chebyshev or Legendre collocation method for solving problems in
