Electronic Structure Modelling of Singlet Fission in Organic Photovoltaics [PDF]

open access: yes, 2018
Singlet fission is a multiple-exciton-generation process found in organic materials that could help to enhance the efficiency of future photovoltaic devices, by overcoming the Shockley-Queisser limit.

Action functional as an early warning indicator in the space of probability measures via Schrödinger bridge

open access: yesQuantitative Biology, Volume 13, Issue 3, September 2025.
Abstract Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states with Onsager–Machlup action functional, to investigate the evolutionary transition dynamics ...

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.

A solution of one dimensional Fredholm integral equations of the second kind [PDF]

open access: yes
Fredholm integral equations of the second kind of the one dimension are numerically solved. It is proven that the numerical solution converges to the exact solution of the integral equation.

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.

VICTOR VALENTINOVICH NOVOZHILOV: A MARXIAN MATHEMATICAL ECONOMIST—IN HONOR OF THE 120th ANNIVERSARY OF HIS BIRTH [PDF]

open access: yes, 2012
This article attempts to present the important contribution of Victor V. Novozhilov to Marxian economic theory, the proof that the theory of optimal planning is the proper field of general economic equilibrium theory and that this theory, by fully ...

Approximation Theorems for Complex $$\alpha $$-Bernstein–Kantorovich Operators

open access: yesResults in Mathematics
AbstractIn this paper, we introduce the complex form of$$\alpha $$α-Bernstein–Kantorovich operators. Respectively, upper quantitative estimates for the complex$$\alpha $$α-Bernstein–Kantorovich operator and its derivatives, Voronovskaya type result and the exact order of approximation of these operators are studied.
