Uncertainty‐Aware Coordinated Transmission‐Distribution Dispatch via GNN‐Augmented Distributionally Robust Optimal Power Flow

open access: yesIET Smart Grid, Volume 9, Issue 1, January/December 2026.
The proposed LA‐DROPF framework integrates graph neural network surrogates with Wasserstein distributionally robust optimisation and CVaR tail‐risk control for coordinated transmission—distribution dispatch under deep renewable uncertainty. A hybrid Benders—ADMM decomposition enables privacy‐preserving multi‐area coordination with formal convergence ...

New Iterative Method for Solving Nonlinear Volterra–Fredholm Integral Equations Using Bernoulli Polynomial

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
The work is aimed at proposing a novel iterative technique based on the combination of two powerful Taylor′s and Bernoulli polynomials to solve nonlinear Volterra–Fredholm integral equations of the 2nd kind. The main contribution of this work is the development of a Bernoulli–Taylor iterative framework in which Bernoulli projection is combined with ...

Identification and estimation of continuous‐time dynamic discrete choice games

open access: yesQuantitative Economics, Volume 17, Issue 1, Page 254-296, January 2026.
This paper considers the theoretical, computational, and econometric properties of continuous‐time dynamic discrete choice games with stochastically sequential moves, introduced by Arcidiacono, Bayer, Blevins, and Ellickson (2016). We consider identification of the rate of move arrivals, which was assumed to be known in previous work, as well as a ...

On Newton‐Kantorovich Method for Solving the Nonlinear Operator Equation

open access: yesAbstract and Applied Analysis, Volume 2015, Issue 1, 2015., 2015
We develop the Newton‐Kantorovich method to solve the system of 2 × 2 nonlinear Volterra integral equations where the unknown function is in logarithmic form. A new majorant function is introduced which leads to the increment of the convergence interval. The existence and uniqueness of approximate solution are proved and a numerical example is provided

An Optimized Block Hybrid Spectral Simple Iteration Methods for Solving Nonlinear Evolution Equations

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT This study presents a new optimized block hybrid method and spectral simple iteration method (OBHM‐SSIM) for solving nonlinear evolution equations. In this method, we employed a combination of the spectral collocation method in space and the optimized block hybrid method in time, along with a simple iteration scheme to linearize the equations.

Multivariate Neural Network Operators: Simultaneous Approximation and Voronovskaja‐Type Theorem

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 11, Page 10669-10677, 30 July 2025.
ABSTRACT In this paper, the simultaneous approximation and a Voronoskaja‐type theorem for the multivariate neural network operators of the Kantorovich type have been proved. In order to establish such results, a suitable multivariate Strang–Fix type condition has been assumed.

Using decomposition of the nonlinear operator for solving non‐differentiable problems

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7987-8006, 15 May 2025.
Starting from the decomposition method for operators, we consider Newton‐like iterative processes for approximating solutions of nonlinear operators in Banach spaces. These iterative processes maintain the quadratic convergence of Newton's method.

Solving Large‐Scale Unconstrained Optimization Problems with an Efficient Conjugate Gradient Class

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
The main goal of this paper is to introduce an appropriate conjugate gradient class to solve unconstrained optimization problems. The presented class enjoys the benefits of having three free parameters, its directions are descent, and it can fulfill the Dai–Liao conjugacy condition.
